Hi,
Thanks for getting back to me.
Normally this is due to the text being within a field.
To confirm that it is a field, press command+ F9 (or fn-F9) to toggle on the display of field codes and see if your text is contained with the symbols {}
Use command+ F9 again to turn off the display of the field codes.
If your document contains lots of fields, and your Word preferences are set to highlight fields as "Always" then those fields in the document will always show with a grey highlight.
However you can change this by doing the below:-
Go to Word
Preferences
View
Field shading: "Always"
If the above do not change anything then please try the steps below:
Select the text,
Go to Format
Borders & Shading
On the Shading Page, select None.
Give back to the community. Help the next person who has this issue by indicating of this reply solved your problem. Please click Yes or No below.
I look forward to hearing from you.
Many thanks
