Hello @Bohdan_Martynenko!
When you are editing an app, you will always be on the latest version of the app.
The releases and environments features can be confusing, it seems you are editing the application, where you are seeing the latest version which is expected.
I have been reading into this issue as I have been having my own trouble getting things understood. This blog post was really helpful for me to understand this better.
When you push to publish a release it will update to the latest version, but when you are editing the app it will be building on top of/in front of the head of the app where you might have to change the query to test with the table you want and then push to live once things are working as intended.
There is more info on this in our docs here which I highly recommend reading. Let me know if either of these two were able to clear up some of your confusion!
