The picture isn’t loading for me. It looks like the markdown got wonky and it is trying to be a code lock.
My understanding is that yes, the CT’s are different. The Main CT’s I believe are more highly calibrated and specifically to your Sense monitor. Where as the Flex sensors are not specific to your monitor. I’m not sure if that just means that if you leave it the way you have it, its possible your measurements just won’t be as accurate as they can be, or if detection will be impacted as well. Ultimatly I think it would be best to get the correct CT’s on the mains, and ensure they are also in the correct port.
If you perform a Data reset, it should let you start over and re run the setup wizards etc…
