with command "qlmanage -m plugins | grep skp" or "qlmanage -m plugins | grep Sketch" not reset icon to show quicklook. Just with command "qlmanage -r" can reset and show correctly quicklook, but it's for a moment.

It's ok. Thanks for try to help 👍
I hope someone else can help me, or new MacOS Mojave can fix the problem. Thanks

No, those commands won't fix or reset anything, they can just help diagnose what is going on.

Yes, and I have updated the MacOS to Mojave but still does not solve the problem
