Door/Window Sensor goes back to closed

Hello,
I have a few Tuya TS0203, everything works good and my automations run smooth.
But there is a problem, if i leave the window open for like 30 or 60 minutes, the state is changing back to closed, even if its still open.

I am using Zigbee2MQTT and the MQTT Integration.
Is there some configuration i missed?
An yes, i think its a Zigbee Problem, not specific HA. It is also closed in Zigbee2MQTT.
Greetings.

I switched from Zigbee2MQTT to ZHA and now everything is working.
