BaseCamp vs. Zumo Map Version Discrepancy

[m185945]

I was using the BaseCamp "Send To" option to send some recent routes to my Zumo XT. The routes transferred but with the following warning:
"Route(s) set to zumo XT were recalculated because they was created on a map that is not installed on that device."
I understand what that message is implying but I think it is wrong based upon the .jpg attachment provided. It appears to me that both the zumo and BC are using the same North America map version 2024.1, therefore, I do not understand why BC is calling out a map discrepancy. Can anyone provide an explanation and/or a solution?

Is it possible that the route was created in BaseCamp with a previous map?

BC
Check the correct map version is selected.

Edit ... Options .... Device Transfer
Untick all checkboxes.
Press 'Apply to all devices'

Rename your route (eg Add V2 to it)

Recalculate the route

Try again.

Yes, it is possible it was created with an older map. Thank you for the idea. Sometimes I reuse routes from previous trips and I invert the direction. In that example it "seems" like a new route, but in reality it was created with an older map. Thank you again.
