Type size bug

Question

Photoshop CC (most recent update as of Jan 6, 2014)
Operating system: Mac OX10.9.1
Problem: Type elements in my PSDs don't know what size they are! This happens one of three ways:
A text element dragged in from another document with the same resolution renders at a different size than it started as
The text size field says a text element is one size if I select the layer, but a different size if I select the individual characters
If the text element has a paragraph or character style applied (overrides cleared) it will sometimes render at another size (today's example: the style declares the some text should be 5px, but it renders at 7.79px-- overrides have been cleared)
The only reliable solution is to delete the problem text and start a new layer.
Has anyone had any of these problems? And more importantly, does anyone have a solution?

Thanks for the reply, Dov. 
In this example I was using Trade Gothic, but updating this paragraph style with a new font didn't fix the problem. (To be fair, I use Trade Gothic almost all the time so I haven't had much opportunity to really test if this problem exists with other typefaces.)
A text layer showing one text size if I select the layer, another size if I select individual characters happens fairly often and I haven't seen a relationship between the two sizes a text element says it is.
A text layer showing a different size than its paragraph style (overrides removed) is almost 2x the size it should be. (if the size is defined as 4pt, text renders as 6.23pt; 6pt renders as 9.35pt; 17pt renders as  26pt; 48pt renders as 74pt) These layers were behaving correctly before I defined the style.
In the same document, if I create a new text layer and apply the same paragraph style to it, the text renders at the correct size.
So far I've noticed the problem tends to happen only if I drag a text layer from one document to another (even if they share the same resolution) and recreating each text layer has been the only reliable solution. Just not a very efficient one.
