[BUG] Power text not working

[Caaethil]

See lua error and images.

I imagine this is a more general issue with texts, but for the example I've tested: I am trying to add a simple number to my power bar to show my Runic Power total. No matter what I seem to do, the text doesn't appear, and I get lua errors like the one below.

Configuring the text and then reloading my UI seems to also sometimes mess up the appearance of my personal resource display (see last image, where the bar scale/position is off - I think it's just ignoring some of the scale and offset configuration I've done to the bar in the addon settings). This can be fixed by disabling texts and reloading my UI.

Love the addon, thanks!
