AB symbols missing on F10 map (Caucasus)?

When checking the F10 map on Caucasus (during Argo campaign mission 7) in DCS 2.5.2.17599 Open Beta, I missed most of those blue airbase symbols. Only very few AB had the symbol (see screenshot). Therefor it's also not possible to click on the AB to get the Airdrome data for most AB. Sukhumi and some in the South seem to be the only AB with the symbol anymore. Batumi and all the others don't have the symbol anymore.
