Another possibility is a problem with your termbase. Try deactivating term recognition - if the "curly brackets" disappear, there's something wrong with your MultiTerm database.
Sometimes it's enough to just recreate the fuzzy index (CTRL-Z); if that doesn't help, it's best to export, recreate and rebuild the database.

I had the same problem recently and switching term recognition off fixed it for me.
