Shelly 2.5 works in roller shutter mode but can't be calibrated and show 0 consumption

Hello guys.

Shelly relay is updated to the latest firmware 20230503-095750. It works in roller shutter mode fine. I can open and close my water tap.

But, it can't be calibrated. The power consumption is always 0. Shelly exposes position "-1%". Looks like something went wrong. And the calibration process can't be completed because the power consumption is always 0.

Only 2 shelly's that works with water taps have this issue.
