Hi @DanBihari,
Taking a quick look at your xslx form, the expression in the choice filter is incorrect. As the result of a select multiple question is a comma seperated string, you can not use the status = ${Staff_Unit} expression, as the string in the choice sheet status column would have to match exactly the comma seperated string.
If you use selected() in the choice filter expression, it will work as expected as follows:
selected(${Staff_Unit},status)
I tested this with your xlsx file and works great.
Regards,
Phil.
