Great! I am glad it solved your problem.
I was lucky to notice the missing units a few minutes after changing just this one checkmark, so it was easy to redo in my case.
Hello. I just had the exact same Problem and was able to find what is causing the problem.
In the HWinfo32 Sensor settings, if you remove the checkmark at "show colums - show average" the units in the gadget disappear.
Setting the checkmark again will also display the units again.
Maybe...
