Fresco turned my layers into PS Read Only

I created an illustration in Fresco. After closing and reopening it in Fresco, I got a message advising that some of my layers were unreadable because they contain Photoshop FX. The illustration has a lot of adjustment layers, but none of them were created in Photoshop ... they were all created in Fresco so should be readable in Fresco.

I did some research online and found this problem going back 3+ years with no solution. However some of the links to information were so old, they're now dead so there could be some solution to it I can't find online. Anyone know why this happens, how to avoid it, or how to fix it?

I was hoping to swap from Procreate to Fresco and this was my first illustration using Fresco as an alternative. Pretty disappointed if this is an ongoing problem - I don't see how Fresco has any reliability/credibility for someone like me who illustrates for paid clients if you can't reopen a file to continue working on it!
