Dolphin icons keep refreshing at open

Hello
I have kubuntu latest version.
I have installed icoutils to display windows apps icons.
Each time I open dolphin and open a folder with windows apps, icons keep loading. I have 10/15 windows apps and it takes 1/2/3 seconds to load icons. This happens each time I open dolphin.
On debian this doesn’t happen. Must be stored somewhere or cached.
Any one encounter this? Or have a fix?
