Why does mapping set FBDI create rows for disabled GL values

Summary:

Mapping set FBDI creates rows even if output values are disabled in GL value set values.

Content (please ensure you mask any confidential information):

Disabled value set values (for natural account segment in this case) rightly cannot be seen in the output column dropdown in the mapping sets. It also gives error if we try to upload such value through import .csv from the front end. But it does allow/ creates rows when imported through mapping set FBDI. I was expecting to get error when disabled values are imported through FBDI.
