Hey there, @Arkadiy K., let's jump right into this!
Based on your screenshots, it seems that the files you're referring to are waiting to be synced. At least this is what the icon is about. You can see more about this here.
Essentially, it's in the "queue" waiting for the changes to be synced.
Do you notice the same dotted, cloud icon even when your app's syncing status is up-to-date?
Let me know more, and we'll take it from there!
