Problem with shadow

ENG: I have a problem with shadows. They do not appear on the edge of the screen.
RUS: У меня проблема с тенями. Они не появляются на краю экрана.


I think this might be a mesh bounds issue:

Does increasing the bounds slightly help?

It didn’t help me or I did something wrong.

Then I’m not sure, sorry…
