I will likely be away from the computer most of today, but here are some thoughts and questions that may help lead to an answer;
1.) Your post did not mention the original reason for attempting a calibration. That is important because this is likely to now be a combination of more than one problem.
2.) When you check performance on the hardware monitor, do you get good, steady readings? Need to know the answer for both now, and before you did the calibration.
Speculation:
1.) Some of your controller contacts may have contamination or corrosion, and some of the various connectors and ribbons inside the controller may have the same issue. The "easy" fix for this is to remove the back panel of the controller, unplug everything and plug them all back in. Then see if it makes any difference on the hardware monitor.
2.) Exercise all the "pots' (control sticks and sliders) Again, check for any change on the hardware monitor. There are some other threads on the forum that discuss how to clean up the 'pots' if further action is needed.
3.) You will need to rerun the FC board calibration. If the calibration was run with damaged or contaminated components, the calibration values will be wrong.
4.) I recommend using the instructions in the following thread, It covers a couple points not mentioned in the video above.
Most cases of erratic behavior and unwanted bias in the ST10 Hardware Monitor are caused by contamination, corrosion or wear in the affected controllers themselves. But not always. If you replace your flight control board, or if the board gets out of calibration for any reason, it will show up...

5.) I would not recommend "factory reset" or "firmware upgrades" at this point. At least until you have identified the specific issues.
6.) And, of course, the possibility exists that one or more of controller boards have simply failed. Those will require replacement of the board(s), or a new controller.
