Etar logo is missing in lock screen mode annoucement

[Moostek]

Hello, I face the issue with Etar announcing me that I have a new event in the mode of lock screen. I use "Hide sensitive content" Android setting, so just blank announcement with an app logo is shown on the locked screen.

Normally there was Etar logo, but now the logo is missing and there is just blank white stripe. Other apps, such as SMS, Dialer etc. they show their icon correctly.

Can you fix it, please?

PS: Android 9
