Hi,

Our tracker updates the maplist when the map has been played on a server.
Although your map is in our database, it is possible our tracker won't enlist it yet, when it hasn't been played.

The B5 version you see in our list, is the official B5 version of your map. It's better to change BSP names for each new beta release, then our tracker can find the new map as well.
Now it considers B6 as B5 because of the same BSP name.

For a next release, it's highly advised to pick a new BSP name corresponding to your mapversion.
