Problem change password


I published my botpress done locally on a heroku server, I can change my password on the application, my new password works, but after x minutes, the old password becomes the password of the account.

Do you know where the problem comes from?

I completed, this is not only password problem. After the first connection when session timeout every elements of config disappear: bot configuration (name, picture,…), login and password of admin user. We test the bot on a website and we see that its name and icone picture disappear
On Botpress Admin Panel we have this message
“This is the first time you run Botpress. Please create the master admin account.”
