PS4 Not allowing me to continue game after exiting

I've read posts about this happening but couldn't really find any information that's specific to my problem. For years playing Isaac on PS4 I could exit a game and then go right back to continue it whenever. Only in the last year or so did I notice that the Continue button is greyed out permanently. This happened after I got Afterbirth+ and I read some people noticed that but it was mostly people playing on Steam.

I bought Repentance a few days ago (I know. It's been out for years but I only felt like I got the most out of AB+ recently) thinking it might fix the problem but it didn't. Weirdly enough, I did a run on my partner's PS account by mistake and exited the the game and the continue was there and I was able to pick the run back up, but when I switched to my account, the option is still gone. Mine is the main PS account, for reference.

Is this just a glitch that I'm forever gonna have to deal with, or is there something I can do with my account to fix it?
