In game's menu always shows Xen image instead of the image of the chapter I am playing

Hello all,
In game’s menu always shows Xen image instead of the image of the chapter I am playing.
Isn’t it suppose to show the image of the chapter that I am playing?
As you can see on the screenshot I posted I am playing POWER UP chapter, but the image is showing Xen chapter.
I tried deleting black mesa folder and redownloading the entire game from steam, but it did not help.
Any ideas how to fix this?
Thanks in advance!

I had a similar issue myself after one of the updates - these instructions solved it for me:

It worked. Much apreciated!
Regards
