Disappearing views when placed on drawing sheets

[AP23]

When I organize my views, I always make a view parameter to group views according to their representative portion of the project. I noticed today a very strange behavior when I place views to sheets. They disappear out of the "view" tree in the project browser. I can regain acces to them through the sheets or when I put the view browser back to "all". Is this a SP3 bug?

Check your browser organization and make sure the Filter settings are not hiding views placed on sheets
Filter > Sheet Name equal to None

Solved........It was set to filter by sheet name. Thanks for the fast reply.
