Route detail in net containing TZT9 and TZT2-12

I have a new installation which contains (among other things) a TZT9 and a TZTL12F. I can import routes in GPX format to the TZTL12F via USB drive and as advertised they transfer automatically to the TZT9.

On the TZTL12F I can do Home > Lists > Routes > select the route > Detail and see all the waypoints, TTG, total TTG, etc. When I look at the same route on the TZT9 (transferred from the TZTL12F), the Route Detail is empty. (When I create a route on the TZT9 directly, the detail does show up). Is this a known restriction?

We have seen some route details showing up blank with the TZT software and we are being told this will be resolved in the next software release. When importing or exporting we recommend you use the TZD format. We have recently seen some duplication issues if you use the GPX or CSV formats.
