Not seeing the latest F5OS-A when running Journeys

Hello,

we're looking at the Journeys migration tool for migrating from the i-series F5 to the r-series F5 and, when running this utility in the off-mode, the latest F5OS-A that is presented to us is 1.5.0 as opposed to 1.8.0.

IS this a bug in Journeys or has something to do with the fact we're running it in the off-mode?

Thanks.
