I have similar problem with current git version that Ekos doesn't seem to reliably register devices that are already connected in the INDI server when Ekos connects to the server. This causes boxes in scheduler to be grayed out, but also causes other issues like crash in align where the code tries to access mount device via a null pointer. Disconnecting and reconnecting devices after connecting with Ekos partially works around the issue, but for some reason capture tab doesn't seem to notice the filter wheel and doesn't show filters which prevents me from actually capturing anything as my sequences have filters set and capture just shows -- and doesn't proceed. Filters are correctly shown in align and focus tabs though. I have quite full set of devices from Ekos point of view (mount/cooled camera/focuser/filter wheel/dome/dustcap/lightbox) and they seem to be a bit randomly registered or not, usually not. Might be a timing issue due to all devices getting "connected" at once when Ekos connects to the already running INDI server?
