Rotax Registration With No Prop Choice

[ADK-Flyer]

I'm going through the process of registering a 912is engine and I'm at the section for prop choice which is still being decided. Can you not register until you've decided on this? I don't see a selection for skipping it.

I wanted to update this since apparently this is a known issue with the registration process and there is a work around which is what I did. Basically the work around is you just put in a prop that you might use. I wasn't sure about doing this as it almost seems like they use the info as a waiver if there was say a gearbox issue later they could say well that prop you chose wasn't correct for your engine. I wasn't super concerned about that though and just picked an E-prop that's commonly being used. I'm almost 100% sure I want to use an E-prop I just want to do a lot more research before I decide.
