Outlook (o365) - additional search filters remain filled

Hi Guys, 

 when user sets additional search filters in Outlook (o365), the filled values are not cleared after switching to different mail folder. Search filters are cleared after removing additional filters at all and adding them back again. I would appreciate if "favourites" additional filters would stay, but would be cleared after switching to different mailbox, mail folder to be able use them again with empty values. 

Thanks for any suggestions, 
Ludek
