Your post isn’t very well to the point.
First, if you have problems with the development binding, this won’t get any better when changing to the standard binding. W.r.t. FGRMs, it’ll definitely get worse as the standard binding does not support Fibaro proprietary commands, so i’d advise to install the development binding. Note this is not the same as the OH2.3 snapshot binding.
Second,
What do you mean by that ? Use habmin or PaperUI to check the device, all parameters should be there. Compare them to the matching Fibaro manual and Chris’ database and tell if there’s truely one or more missing ( I don’t believe so).
If what you mean is how to operate lamellas, you need to create a dimmer type item for the blinds_lamella channel.
