Popp keypad firmware version


I have some issues with the Popp keypad, you may say it’s sometimes a bit unstable. Have done a lot of trouble shooting and the conclusion is that I suspect the Z-wave network. Before digging into this deeper I contacted the Aeotec help desk to find out if my Popp keypad is running the latest firmware version. According to the Popp app in Homey it is running version 263.
The thing is that the Aeotec helpdesk has never heard of a firmware version 263. They claim that it should be 1.08.
@mapulu, do you know from where the Popp add gets that value of the firmware version?
