Xform hides choices for fields with both relevance condition and choice filter

1. What is the problem? Be very detailed.
When rendering a xform, choices do not show for fields that have both relevance condition and choice filter. The form works perfectly when I do away with either of them.

2. What app or server are you using and on what device and operating system? Include version numbers.
I'm testing this on ONA.io

3. What you have you tried to fix the problem?
I have applied a workaround by combining choices with the main option. For example, for a question on vaccines (OPV, PCV, ...) and doses (1, 2, 3) based on selected vaccines, I combined them to have vaccines + doses (OPV 1, OPV 2, OPV 3,...)

4. What steps can we take to reproduce the problem?
Configure a simple form based on the below design doc captured below

5. Anything else we should know or have? If you have a test form or screenshots or logs, attach below.
