can not delete databases in privacy

I have a problem of not being able to delete specific items under Safari preferences privacy tab, specifically database items.

At least daily I first delete caches under the developers menu, then I remove all but a select number of entries under privacy which are mostly financial entries. For example, I do not use Google or Facebook and do not want them snooping around, but a lot of sites will automatically add Facebook or many Google items. I have checked asking not to be tracked, preventing cross-site tracking, and block pop-up windows.

If I get a certain database item deleted and just scroll down, the item will reappears. Further attempts with that item will usually not even temporarily delete the item until a reboot.

There are now 3 site databases that will not delete or stay deleted and have been trying for the last five days. This has happened about a month ago and the only way I found to remove the stubborn database item was to delete all, which included items I didn't want to delete. This causes a problem as I have to reconfirm with a bank or other financial institution that the computer is authorized to access the account because of multi-level security. These same security steps happen on iPhone and iPad with these institutions.

The databases currently non-removable are from sites I have visited (Sony, Epson, Adobe).
