New update broke my slider functions

I have a few sliders in my project with references to functions with dynamic floats.
They were working perfectly fine in Unity 2019.2.3f1 but aren't detected in 2019.2.6f1.
I don't have a clue why but it must be a bug.

 

it's a bug.... and Unity doesn't care isn't interested to fix ...
fill a bug report if you have the time...
Unity doesn't do any testing anymore... it's now up to the Users...
it's way cheaper if you let the community find the bug's...
and if you found one.... no thx no feedback... nothing for spending the time to document the bug...
it's really frustrating now...
