Smartwings blinds driving me crazy

Pairing with zigbee2mqtt went fine.

I set the lower and upper blinds settings per instructions with key combo on physical remote.

But the down arrow when blinds are up on my blinds card in HA won’t do anything when pressed, it is like they are reversed. But the slider bar is correct and works. As seen in photos attached.

I tried key combos on the remote but that just inverts the slider and makes it wrong.

I also tried inverting settings in Zigbee2mqtt but that just inverts them and makes them wrong again.

Anyway I can get these right?

IIRC the blinds manual has instruction on inverting the up and down configuration on the device - did you try that?
