Missing icons in Add/Remove Programs - How Can I Fix?

Hi, I just installed a suite of programs that I purchased and most of the icons are missing in the Add/Remove Programs. I tried re-installing and still the same issue. How can I fix this? Where are the icons sourced from? I've contacted the company but have yet to hear back....so hopefully someone here could put me on the right path!

And while we are here (this could probably be another thread tho)... why is the search engine in the Add/Remove so damn slow to show results??! Its been extremely slow for years and I keep hoping a Windows update will speed it up...

I'm on Win 11 Pro, ver. 22621.1778, with 58 apps installed and I find it VERY rapid.
