Description

Advanced filtering dropdown for HGrid shows field names instead of headers as it is for other grids

• igniteui-angular version: 20.0.15
• browser: Chrome

Steps to reproduce

1. Create a sample with hierarchical grid and advanced filtering
2. Assign headers to all fields, choose some names that consist of more than 1 word

Result

Dropdown fields are in camelCase- taking the field names instead of the header names of the columns

Expected result

Dropdown fields should show header names with separate words where there are multiple words
