not saving remote login data

after a fresch installation v3.3.8 (delete AppData\Local\Atlasian and AppData\Local\Sourcetree completely) SCT does not save remote login data for bitbucket. Will see a red exclamation on button "Remote". After clearing this problem by edit url (Remote account) in settings the red exclamation disappear and I can work. Than after close and reopen SCT the red exclamation will displayed again ad the users remote accout is set to "Generic Account / Generic Host"
