Limit to how many prefabs you can bookmark?

Been going through and bookmarking a lot of prefabs lately, and then when I went into forge I noticed that like the last 10 or so I bookmarked did not show up in the prefab list. I removed a couple prefabs from my bookmarks and then when I went back in that exact number of new prefabs showed up.

Is there a hard limit on how many prefabs you can bookmark?
