EnumList adds an extra space

Using Appsheet API, I edit the records in my appsheet_db and I noticed that one of the columns, col_a which is an enumlist with item separator as “,” has some unintended behavior.

I pass this value in col_a.

app_1 - Development, app_2 - Development

But when I retrieve it back (GET), it returns as this value. (Extra space after Development.

app_1 - Development , app_2 - Development

Based on related articles:

Is this the intended behavior? Where the delimiter is always
space , space

where ,is the item separator?

This is expected behavior. Space-comma-space is the default delimiter in columns of type EnumList and List.
