Alexa opens Covers, If I turn light on via voice

Hi there,

since a couple of weeks a experience the issue, that Alexa closes my covers, when I say the command “Alexa, turn the light off” via Alexa (and opens, if I turn the light on).

Covers are controlled by Shelly 2.5 with native firmware connected to Homeassistant. Via Amazon Alexa Integration Covers are handed over to Alexa. They are included via simple command via its name in my config (no further definition).

It always worked like a charme, but there was apperently a change, which I did unintended. I think I opened the “new” shelly App once. Could this be the reason and how do I revert changed?

Many thanks!

Any idea how to tackle that? I assume this should be an Alexa issue, but I did not conduct any change and all covers are assigned as blings (German version: “Jalousien”) in the Alexa App.
