The "_" Suddently Appears

Afrter removing unused addons today, I have issue with data shown on administration panel of the shop.

The "_" appears all of the suddent before order id, and some of the column titles and the option to chose how many results to show per page is totally messed up.

Attached screen shot with the above issues highlighted in Yellow.

Anyone have any idea what could cause it and how can I fix it?


the language variables may have been lost.

copy the text you see and search in languages for it

then rename

Try to update translations on the Administration -> Languages -> Manage languages page


Thanks for the help.
