Description:
Although word completion is active, I do not receive any word completions. I have already tried to solve the problem once. Renamed the user data so that it is recreated. But even then it does not work. Switching off the function and then reactivating it did not help either. 

Steps to Reproduce:
1.Activate word completion in the settings
2.Enter words in the list
3.Write the words. 

Actual Results:
No word completion suggestions appear

Expected Results:
After entering the first three letters, suggestions for additions should be made


Reproducible: Always


User Profile Reset: Yes
