Thank you for the suggestions, here's where I'm at:
"Try with another language to see if it is English only." - I tried 2 other languages, and both had the same issue (displaying the tags)
"Query cmn_captions_nls for the string to see if that comes from the database" - I queried, filtering on 'en' & name or descr like '%excel%' and didn't retrieve any comprable results.
"Try another browser and browser version. (Which one are you using?)" - I usually use IE 6 (where I noticed this issue. I used Firefox 3.6.16 and had the same results.
"Have you tried restarting the apps?" - Yes, several times.
"Was there any change made to union_view_en.properties file" - None that I'm aware of. I'll take a closer look, but I don't know why a change would have been made to this file. I'll post an update if I find otherwise!
Thanks again for the suggestions!
