Closing and opening the first panel, the filters set still remain

Search TITLE Begin with HUMAN and set filter Record type "Bibliographic records". The result search is displayed in the second panel, with all columns foreseen (Date 1, Date 2, Format, Subject and so on). Closing the first panel and reopening to do another search the system will reset all filters previously and the behaviour is correct, but excuting the search, the result is still related to the bibliographic record, because I see the colums Date 1, Date 2, Format, Subject and so on ... (these columns are displayed only when you applied the filter Record type--> for Bibliographic record).
