I created a template and set up all of the styles correctly, as with every other template I've ever made.  However, I have never run into this problem before.

I created the template to match a client's style/look.  They use a font called "Gill Sans MT."  My Normal style is set to this, and my TOC styles (TOC 1, TOC 2, TOC 3, etc.) are based off of the Normal style.  My Heading styles are also based off the Normal style and use the same font.

For some reason, the TOC in the document is populating with two different styles.  The actual Heading text is showing up as Arial font, but the tab leader and the page number are showing up in the Gill Sans MT font (see below).

Any idea what's going on here?  I have tried modifying the TOC styles, inserting a new TOC, basing the TOC styles off of "(no style)," changing the Heading styles, clearing the formatting on the Heading styles, etc.  I can't get anything to work.
