I think you'd need to replace them one-by-one not 'Replace All'.

Thank you very much for your response Jackie. It almost worked When I have, for example:

C H A P T E R  V I I I

after applying your code, I have:

CHAPTERVII I

Where my strings are all in uppercase, I can use your code with \b([A-Z])\s+(?=(\w\s+\w)) and case-sensivity enabled and I can do the work at once. So, if it were possible to solve the issue, your RegEx is very usefull.
