Unable to persist changes on Api-Designer (local)


Hi there, i’ve successfully installed Api-Designer on my machine.
After adding an API spec, and hitting save on the UI, it does say it saved. However, the changes are not actually persisted and get lost completely upon page refresh or between server restarts.
This was not the case in the old version of API Designer.

I lost all my previous files and can’t seem to be able to save new files.

Any idea?
Where can i find more logs for the running grunt server and how can i see the local database?

Thx in advance,
