Aminopyralid contamination

Hoping I maybe able to get some advice on aminopyralid contamination 😭😭. I'm pretty sure I'm seeing signs of it in my broad beans, some are looking all twisted up (many moons ago i worked on farms and it looks very like weeds that were sprayed with herbicides).
Will this breakdown in time ? I have filled 3 large raised beds and a greenhouse base with between 8 and 12 inches of homemade compost and throughout last year all the compost was mixed up extensively when I turned it and moved form bin to bin.
Is the job knackered ? have I made a huge mistake here ? I think it's either come from a small batch of horse manure or my mum's garden which may have been sprayed by her garden maintenance company. Any help greatly accepted

The "no-dig" blogger references Charles Dowding experiencing a similar problem and planting the area with sweetcorn instead. The theory being that sweetcorn is similar to grass (being a monocot) and, hopefully, not susceptible to the chemical.
Until I scanned the piece I was unaware that the chemical does not break down in the composting process.
It reminds me of a film I've recently seen called 'Dark Waters' about Du Pont's cover up of the poisoning of people and animals living near to their Teflon production plant.
I have used grass cuttings from 4 different gardens in my compost and unbeknownst to me the lawn care company have used the same said chemical. I've only added the smallest amount of horse manure to the compost and I'm not sure it was in last year's produce.
All the info I can find says that the product only breaks down when in contact with soil Bourne bacteria, all advice so far is I need to rotovate the beds to mix my compost into the soil. Not easy when it's at least 6 inches now it's compacted down and 12/14 inches in other places. The soil below is also full of rubble, a legacy of buildings being pulled down on the site many years ago with soil spread over. I haven't been able to remove all the rubble as we've already removed 50 tons in the last 4 years
Anyway I'll see how I go, it's quite a disappointment
@JennyJ I will stop collecting from anyone who uses chemicals on there lawn (I only take grass clippings in the main) thing is I'd never heard of the aminopyralid problem till only a few weeks ago.
@Allotment Boy it will only breakdown if it has come into contact with the soil bacteria for prolonged period. Am considering buying a load of topsoil and adding on top of the beds then hiring a big self driven rotovater to mix it in.
It's such a shame that manure or compost material can't be used without and concerns.
I could do with some advice too please. Planted my tomato 🍅 seedlings into some expensive shop bought compost but germination has been uneven and some of the seedlings are stunted and deformed.
They've been kept in the same propagator and exposed to the same grow light etc so I can't think of anything else that might be causing it.
Very annoying as it was about £10 per bag 😕
Interested in opinions from anyone who's dealt with this before and thanks in advance 🙏🏻
