Problem with Code Completion in Eclipse ATD

Hello all, the behavior of the eclipse when I am writing ABAP changed and I cannot find where.

Previously, when it suggest sth it was i a black box and if you wanted you press TAB or CTRL-SPACE to find sth else. Like the below picture.

From the weekend sth changed (most probably by me) and the behavior changed. The suggestion goes in line and the cursor at the end of the proposal, like the below picture.

 t is the letter i type and ype is the code completion.

Keep in mind that I am in the latest update of the Eclipse and I am using the DARK theme of Eclipse.

Please for your help as this behavior is very annoying.

Thanks

Elias
