In all 3 of my online leagues the game is randomly adding all these random offers to pending offers in the new patch (24.5.64) after installing it. None are offers that were there before installing patch. Most are minor league contract offers, but I've seen some that are minor league w/ major league option, as well as MLB contract offers. None that I have seen are showing they are pending, they just come up as the player rejecting the offer. But it spams the pending offer page. Anyways I wonder if what you are dealing with is similar and causing the problem.
Here is the screenshots for the developers here too of two different teams in two different leagues:
