Hey there
I found this bug today, through out all my apps.
when user selects a custom value, it appears as null instead of the selected value.
this behavior was consistent in all my apps, and on a new blank app.
I have Attached screenshots below:
where i selected values 4,5,2,7
with default values [1,2,3]

Hey there @CaptainFreight,
Great news — it’s been fixed! 
Custom multiselect values will now show the value, instead of null.
Echoing Alex, thank you for surfacing this issue and thank you for your patience while we got this fixed!
