2010 SuperSports Suspension Leveling Issue

I'm experiencing a bit of a strange issue with our SuperSports. Recently I moved the car from our main garage over to our detached building, and noticed a few days later that the front suspension is not level from left to right (left is higher). I have measured the garage floor and it is level, though the main garage floor where it sat previously was not exactly level, which might be why I never noticed the issue prior, or it wasn't an issue at that point.

The suspension does not sag. I have tested for a minimum of 3 hours: 1. suspension in high setting/jack mode on, 2. suspension in high setting/jack mode off, 3. suspension in normal setting/jack mode on, 4. suspension in normal setting/jack mode off. The ending measurements are the same as the beginning in each scenario except for this: the LH front is ~1cm higher than the RH front in the high suspension setting vs being almost 2cm higher than the RH front in the normal setting. The car raises and lowers fine, as the different settings are selected, and the compressor is not constantly running

As a hunch, I swapped the LH front height sensor, drove the car around the block, and reset the adaption. No change. When looking at the VCDS measurements, the car does see that the LF and RH front are not level: +8.0LH and -11.0RH, and all of the sensors appear to be reading in the "normal" voltage range (at least, they're all reading essentially the same range of fluctuations), but the car just doesn't seem to be able to level out.

I have not yet pulled the RH front wheel, but everything on the LH front suspension appeared fine when I was replacing the sensor. Is it possible that a suspension hardware failure, or alignment issue (just performed about 2 months ago) could cause this type of imbalance?

Thanks in advance!
