Boy, I wish I could tell you what's under the hood!

Sorry - I did not mean to imply you entered the two commas. What that all means is that you can enter Microchords in BIAB two ways: you can do it in that dialog box, as you did, or, if you are up for a real challenge, key them in. The educational aspect of that dialog box is that it does show you what the graphical interface will translate into a code you could have typed in. That's how I spotted that it wasn't coded as a triplet. Make sense? That pattern makes a pulse in your measures like this: Note Rest Note Note Rest Note etc. Say those six things evenly in time.
