CD19 - Writing Tools - Quick Correct Text Not Working

Hi everyone,

im using CD19 and i cant correct a type and replace text problem.

Every time i type a certain word it changes it to another word, so i go into Writing Tools - Quick Correct and add in the correct word I want for when i type that certain word however after saving and i go back and test it, the same error happens it will not accept the correct replacement word i want.

I know I can just click Undo, but I want to fix the problem properly.

Is this an actual bug or am I doing it wrong?

Thank You for any help you can offer

cheers Kev
