This will be indicated next to the form. It will say Filter Applied. You can also check and/or change it by doing the following:

1. Select the Public Folder
2. Select Arrange from View Menu
3. Select Customize form Arrange Menu
4. To remove all filters, select Clear All. You can also create or change the filter in this location.

If All Public Folders are affected and you're not able to see any Public folder information, then there may be a filter applied to all of them.

I would suggest running the command line listed below to return to default views and remove all filters. Type the following (or browse to your Outlook.exe location) and enter CleanViews with the following command line:

Return to your Public Folders and any filters should be removed and the default view returned.
