Some Microsoft Store installed apps doesn't show within Microsoft Store's Library

Hi,

Some apps (not all) which I install using Microsoft Store, e.g. Viber:

Do not show up within Microsoft Store's Library:

Strange thing I noticed, that the main screen 'status' in this case not indicating the Installed state (only if open the app information panel like in the first image):

While .e.g in case of Whatsup the 'status' indicates Installed, and properly shows up in the Library section.

May I ask if this is normal behavior not not show in Library section for some app (like Viber) installed through Microsoft Store, or indeed it should show as well? If it should is there any PowerShell cmd to force Microsoft Store to re-scan all installed app or something similar ?

I already tried to reset and remove/re-add Microsoft Store app, and it did not made any difference.

Many thanks for your time and help in advance!
