Shelly switch values alter themselves on Home Assistant only

Hello. We have shutters connected to Shelly switches, integrated into Home Assistant through ShellyforHass, only because the official integration was giving us issues where the OS would do funky stuff after 4 or 5 reboots and go into emergency console on every boot.
All was working fine for a couple days, then the problem appeared. Here is the card:


We have 4 blinds (“Estore x”), each with a switch for opening (“Abrir”) and one for closing (“Fechar”), and two scripts for opening and closing all blinds simultaneously (these work as intended). When clicked, it’ll perform its action correctly, but after one or two seconds, the switch on the GUI will flip back to Off, while not affecting real-life operation of the blind. Flipping it to On again will change nothing, and flipping it to Off (before it changes by itself) will stop operation of the blind, as intended. This happens on each and every one of them. It’s worth pointing out that the blinds work perfectly fine on the Shelly mobile app.
For a bit, all the open switches would constantly be on the On position, with a similar behaviour to the setting above. I don’t even know what I did to alter the situation, as far as I know this changed by itself.

I got into home automation for the office just a few days ago, so any assistance would be greatly appreciated. If I can send any other information that might help diagnose this, I’ll gladly send it. Thanks in advance, everyone!
