"open with" - keeps asking every time

[haarbeli]

Normally, whenever a file is clicked on, that have several apps capable of opening it, an "open with" menu displayed. For example, an mp3 file, and there is more than one app able to play the file.

You can choose the app to use for opening the file, *and also choose between 'just once' / 'always'*.
Choosing 'always' should set this app as the default app for opening the file, and avoid asking again.

In my case, choosing 'always' does not work. The file is being opened immediately, however the choice is not remembered.
I.E. for example clicking the very same file again, will open again the menu asking which app to use for opening the file.

Additional data:
Doogee X5 PRO
running, Android 5.1
root: it is currently rooted. The above situation appeared fairly long before rooting.

Tried: resetting all default apps, via apps => settings. No effect
Tried: installed "better open with" app. It had no effect, however this is expected, as the app deals with a slightly different issue

Maybe that is a feature. Click once it goes to the always app that you had set previously, click again and it thinks you are changing your mind about which app should open.

"Click once it goes to the always app that you had set previously"

This never happens. Not on the same file not on another file with the same extension

After selecting an app as default, do you get a message telling you how to clear those defaults? If so, are you doing that? This is a common misunderstanding -- that message is only meant to be informative, but some users assume that they're supposed to go and clear the defaults immediately (which obviously negates what they just did).
