How to eliminate the space before the percentage sign

I run SDL Trados Studio 2017 version 14.0.5821.4

The software automatically puts a space between a number and the trailing percentage sign (eg 42.2 %).

This appears when I pretranslate using SDL Language Cloud Machine Translation.

If I delete this space for all such fields using the "Replace" command, and confirm the first segment, the the Auto-propagation goes through all these fields again and puts the space back in again.

How do I stop the software from doing this???

 

Many thanks
