The comments about personal resource don't seem to be the issue. I have the same problem, when using classic mode, the Player Frame floats above the mini map, along with target, and target of target. I too cannot find a way to re-anchor to the classic view bar, next to the mini map.

Expected.
From the SUI6 Survival Guide in discord:
With unit frames being re-wrote from scratch the artwork takes a lower priority than making sure all the new customization and options are functioning. As such not all unitframe art is finished for SUI 6.0 but will be by 6.1
