Multiply blending mode desappeared

Hello everyone!
This is my first post here and I need help with an issue with my blending modes panel. Yesterday I was working on a piece an was using Multiply in a lot of layers. Then, I tried to use it in one last layer and… the Multiply blending option had desapperared from the panel list.

I’ve tried to restart the program, reinstall, but the problem persists. I don’t know if I somehow deleted it accidentaly or whatever…

Do you have any idea how to solve it?
Thank you!

Maybe you just used it from the favorites category, and accidentally deleted it from there. Open the Arithmetic category under the favorites one, and ensure that multiply is ticked on.
