Bug in Rendering Field Label name in Custom Module for Specific User

We have encountered an issue where one of the field names in a custom module is displaying its API name instead of the field label name in the layout. Notably, this issue is only affecting a specific user.

Issue Details:
Expected Field Name: Invoice Date of Delivery (Material delivery date)
Displayed Field Name: API name (as seen in the second screenshot)

Kindly request you to help us resolve this at the earliest.
