InfluxDB binding: cannot clear password

Hi,
on OH 4.0.4 (64-bit docker) I installed the influx binding from the mainui. However, I accidentally entered a database password when I needed the token. Unfortunately I can now just change that password. When I clear it and hit save, the previous password is set again.
Can anyone confirm ? But be aware ! Trying this renders your influxDB inaccessible.

Solved: I had a influxdb.cfg file with an old password set. Apparently that leads to that strange behaviour when used with the UI. Imho the setting in the UI should not be editable when previously configured by a file.
