Term base auto suggest

Hello,

My term base is open and appears in the editor. However, when I reach a word with a red bar (to show that the term is in the TB), the segment does not automatically suggest the translation found int he term base, thus I have to type out the terms manually every time. This occurred suddenly, I have not changed any settings. Any ideas on how to correct this?

See below, no suggestion to auto complete the term found in the termbase.

 

Thank you for your help
