All cover.xxx are failing after restore of Raspberrymatic

Due to an issue with the SD Card i had to reimage my RaspberryMatic and restored the last backup which i do monthly.
Nothing changed inbetween on the Raspberrymatic.
The most parts are working properly (Sensors nad buttons) on HomeAssistant. But anytime i call a cover (HMIP-FROLL) to be closed or opened a error occurs: invalid literal for int() with base 10: ‘’

If i restart HA the service is working for a few sequences and then it is failing again and will continue to fail.
