Problem with filters and MARKEDONLY

Hi,

I have a problem with a filter on a list form. On the form 31 (Item list) I make a filter using the mark property, using a field on the top of the form. On the Validate trigger I mark some items and then put a filter with MARKEDONLY(TRUE). The problem is when I try push the "Show all" button, I get the message "Do you want to rename the record?".

Does anyone know why this message is displayed and how can I show all the records again without getting this message when pressing this button?

Thanks a lot
