Instant Text expansions trigger Word autocorrects

I am using Word with autocorrects turned on while using Instant Text.

Some of my instant texts are pulling autocorrects from Word and expanding, which I do not want to happen.

Turning off autocorrects is not an option at this point. I delete the autocorrects from Word, but every day they show back up.

How can I configure an instant text entry to not expand an autocorrect?

For example:

hmwck will get expanded to high molecular weight cassette K.
What I want is high molecular weight CK.

In this sample, the CK is getting pulled in from autocorrect in Word.

Thank you in advance.
