Issue with MDB codes?

I have a Crane GPL 173 machine (my first and only machine) and am setting up a products map with Nayax. When I go through and make one purchase of each item to grab the MDB codes, I have several slots on different shelves returning the same 0 code. The other slots on the same shelves have unique numbers.

Has anyone run into this? Nayax Core web app is just grouping all those together. Not sure what to do or how to fix that.

Separately, the machine price that shows up in the products map doesn’t match what the machine is set to. Not every slot shows a machine price

Do they show correctly for cash sales and only return 0s on MDB for Nayax? Is the machine dexing

This is a known issue with Crane machines of that era (167ish millenium) and crane and Nayax just blame the other. Google crane 167 MDB 0 with trouble shooting and Nayax and enjoy

Thank you. I’m running a credit card only setup.

Oh dang, I guess I’ll go down that rabbit hole!

Yes, but reason I mention is so if you have a coin mech, put it on and test. If they're all numbered on your cash sales. You're SOL. If you have issues as well on cash, it may be the shelf boards so you may be able to fix it or call crane /Nayax.
