The problem is you have resized (manually squashed) the text area using the Selector tool rather than the text tool.
The text area - Bolsover and area, Derbyshire is no longer 100% aspect ratio, it is 73.83%.
Unfortunately there is no way to change this back with any accuracy in WD MX so you will simply have to delete the text area an recreate it.
Same thing with all the white text below, you have stretched it to 105%.

Always resize text areas using the text tool via the red control points at each corner of the red dashed bounding box and never by using the Selector tool.
The reason is, that while Xara can render squashed or stretched text, browsers cannot.


Designer Pro X is able to correct this via the text aspect control, but WD MX does not have this feature.
