Cover controlled via ZHA reports always "Open"

Hi everyone,
I have 4 blinds in my home operated by Vimar Zigbee switches, integrated into Home Assistant via ZHA.
After a recent update, all of them are now always reported as “open”, even when they’re fully closed (0% position). Additionally, the UI no longer allows sending a “close” command when they’re at 0%, assuming they’re already fully open.

I suspect the issue is related to tilt support — the switches technically expose tilt capability, but my blinds do not support tilt mechanically. I’ve already tried disabling it by setting supported_features: 15 for each cover in configuration.yaml, but Home Assistant still seems to use the current_tilt_position attribute to determine the state.

I’m not sure what exactly changed to trigger this behavior, but it wasn’t an issue before.

Is there a way to fully ignore the tilt values without having to create template covers for each blind just to control up/down movement?
