Date not printing out into document

Hey everyone,

So I have a simple form with three combo boxes that contain Month, year and day. They're programmed to reflect the correct days in the day combo box based off of the month and year. That being said the end result is as follows:

Selection.TypeText Format(cboMonth.Text + " " + cboDay.Text + ", " + cboyear.Text, "mmmm d, yyyy")

Now I have over 200 individuals using multiple forms designed this way and of course 99% of them will get the result of:

March 1, 2018 as an example.

I now have two individuals who have reported back to me saying they get the date printed out three times. Now they are from different regions, I believe one being Israel. So I checked their system settings and everything appeared to be in order there. The system settings were displaying that the long date would print out as displayed in the example above. Where else should I be looking to figure out how to get their computer to register the Format function properly and display the date just one time?

Thank you in advance
