Sorry to hear you are having issues.
Is your system an ARM based system 64bit ? if so Fences not compatible .
and yes those Two instances of 'Fences Settings' are normal and must run.
You didn't mention before that this was a Company Laptop , you may have to
check with your iT people if there might be security software or other causing
Fences to run high cpu usage.
I see you have other software running all together high CPU usage .
If you can't do the clean boot see if iT can help with this .
and report back here .
