My android app keeps updating in playstore even I update the latest version

Question

I couldn't find any similar topic in here or google. I uploaded an app in play store and then I uploaded a new version of it. But now, It always asks for an update in market. I don't know is it due to my code or something. When I upload an update I increase the versionCode and rename the versionName in android studio then sign it

Then I go to play console - select the app - release management - release dashboard

Then I release my new version. I select "Android App Bundles and APKs to deactivate". I don't click "retain" It seems like a stupid post but I don't know what the problem is. I did it before I've never faced such an issue. I do everything like described in here https://customersupport.doubledutch.me/hc/en-us/articles/360001395033-Android-How-to-Update-an-App-in-the-Google-Play-Developer-Console

Finally it always asks for update in the market

I would be glad for any tiny idea. If stackoverflow is not the correct place for this post can you at least redirect me the correct place? Thanks.
