Cant see any of my entity AI's

I'm not being able to see any of my entities' procedure blocks, I've seen reports of these bugs here but I haven't found any concrete answer yet, will I have to delete all my entities and revert? have any way to fix? some give errors like not being able to find the start block others just a gray screen with nothing? If you already have a way to solve it, someone tell me, even though there are not many entities, there is enough to make it very boring to redo everything

Im using the 2021.2 

Its a 1.16.X mod

Sorry if you already have a solution I just wasn't able to solve it with what I found
