Fonts missing in Textedit

The Fonts panel in TextEdit used to show all (or nearly all) of the fonts activated on my iMac. Of late, it only shows Arial, Tahoma, New Times Roman, Trebuchet MS and Verdana (web fonts). (I've looked in Preferences, and don't see any way to specify a document as targeted for html.) I usually work in Rich Text format and save that way. Can anyone tell me how to get my full font list again?

Muchas Gracias!
