Is there a limit to how many personalised food entries we can create?

I prefer to create my own food entries instead of using whatever I can find in the database because I've noticed some major inaccuracies, and also because I prefer to work in grams rather than pieces, servings, cups, etc.

But I've noticed new entries aren't showing up on the list of My Foods anymore, and I don't understand why. I haven't created hundreds of entries so if there is a limit, it's a stupidly small one. Or is the app glitching, does anyone know?

Thanks.
