Hi,
How did you insert the Visio file to Word?
I suggest you check the editing language in Word for Mac:
Go to Tools > Language, select your language, and select OK.
To make it the default for all new documents select Default.
Tip: To prevent having to manually configure the proofing language with each new document in Word, switch on the option to detect the language you're writing. On the Review tab, go to Language, and then select Detect language automatically.
