Ionic Pro, Live deploy - Update runs, although the version is the same/newest

Hi there,
I have a strange behavior with the live deploy function:

I have a certain progress with my code, so i stop developing and push/commit this code to my dev-branch on github. This branch is connected with ionic pro/live deploy and automatically builds a version into the dev-channel.
After that, i locally run “ionic cordova run android” and run this code on my phone.
At the moment, my update logic checks the dev-channel. And strangly it finds and runs an update.

How ist that possible?

The version on my phone and the version on my dev-channel are exactly the same. Why is the update triggered?

I hop, anyone can explain this to me.

Thank you
