ue5 will clean pre-compiled plugin

i have create a pre-compiled plugin using this guide
How To Package And Sell Binary Plugins For UE5

it works fun with Rider’s Build menu.

but it’s Binaries will be cleaned with Rebuild and Clean menu.

since rider is executing ue5’s commands, it means that ue5 itself does not confirm this as a pre-compiled plugin, or sth is hidden behind this article

does anyone know what happened? thanks
