When I open openLCA for the first time after restarting my computer, the first time I connect to MySQL at localhost:3306, only one database (out of three) shows up. If I disconnect and then reconnect, I can see all three. After this happens once, if I close openLCA and reopen, when I connect, all the databases are visible.
I have repeated this behavior three times now (restart computer, open openLCA, connect, disconnect, connect) and it is consistent.
