opening paystub as .pdf shows wrong tab name in Fiori

Hi experts,

when opening my pay stub/pay slip as .pdf in FIORI the new tab that opens is named "$value". but I would like to have the name of the selected pay slip in the tab.

1.

...choose the button "als PDF öffnen"

2. pdf is opened correctly but the tab-name above is "$value".

Thanks for support

regards,

Georg
