[O] why org capture finalise asks for deleting bookmarks every time

[Q]

When I finished typing in a capture buffer, I hit C-c C-c, 
this is what I get in the message buffer, looks like emacs is trying to save
all opened file and then delete backup of bookmarks. How do I avoid all this?
Thank you for your help!
