WP X7 and repeating letters

In Wp X7 the "g" was doubling to "gg" . It wasn't a quickcorrect nor quickword.  I could not find anything in the template, quickwords nor quickcorrect.  So I deleted the WPUS17 template and now all is fine.  If anyone runs across this problem then do this and save the hour it took me to think of the delete key.  Fortunately my template was nothing unusual.
