We also never use any filler directly over lead, as it will turn loose like your paint has. We always have a barrier coat of epoxy primer over lead, then filler over the sanded epoxy.
I've done it this way for decades and it hasn't failed me that I know of.

OK, thanks. Like you are saying in your reply, there are tiny bubbled-up areas all around where this is occurring. Thanks for the info. This should solve those issues.
