Hi, first time post. I have faced the same problem as you and manage to solve it.
Step 1
Go to where your Aida64.exe is. Right Click > Properties > Compatibility Tab > 'Change High DPI settings' > Check 'Override High DPI Scaling' Scaling performed by: 'System' (from the drop down) > Ok/Apply > Restart.
Step 2
RIght click desktop > Screen resolution > make sure monitor icons is scale to 100%.
Then go import the sensor panel again. It should look normal now. Then lock the panel size. Change your computer icons scale back to normal. I am not absolutely sure Step 2 is totally necessary but because i just modded my first panel, but there is no harm to pass you this information. I shall test again when i make a couple more panel for fun. It took me 10 hours of trying to manually change everything before i found this solution buried deep in the forums.
