Reducing multiple choices dependent on previous select_multiple choice selection

1. What is the issue? Please be detailed.
I am trying to reduce the choice options from select_multiple based on the selection from previous select_multiple choice list.
** I am looking for urgent solution, my entire questionnaire is dependent on this primary feature**

2. What steps can we take to reproduce this issue?
I have attached xlsform, xml and csv file below.

3. What have you tried to fix the issue?

solution from Yanokwa works if my list is static i.e. part of choice list.
However, it is not working if my choice list is from external CSV.
I have tried both with search in appearance and select_multiple_from_file with csv name.
Both external CSV options are not working.

4. Upload any test forms or screenshots below.
see attached test form. In column Hint I have highlighted as issue 3 solved and issue 3 not working.
