“TextAutoSize is not supported with the Standard TextGenerator” warning is shown when enabling “Auto Size” in UI Builder while “Enable Editor Extension Authoring by Default” is enabled

Steps to reproduce:

1. Create a project using Universal 3D template
2. Go to Edit > Project Settings > UI Toolkit
3. Enable "Advanced Text Generator" and "Enable Editor Extension Authoring by Default" properties
4. Create a UI Document (Assets > Create > UI Toolkit > UI Document (UXML)
5. Open it in UI Builder
6. Add a Label to the UI Builder Hierarchy
7. Select the Label and in the Inspector expand the "Text" foldout
8. Observe that "Text Generator Type" is set to "Advanced"
9. Enable the "Auto Size" property
10. Observe the Console

Actual results: "TextAutoSize is not supported with the Standard TextGenerator. Please use Advanced Text Generation instead." Warnings are shown

Expected results: No Warnings

Reproducible with versions: 6000.3.9f1, 6000.4.0b9, 6000.5.0a7

Can’t test with versions: 6000.0.68f1 (Auto-Size property not available)

Tested on (OS): macOS 26.2

 

Note:

• Project settings indicate Advanced Text Generator is enabled, and the Label’s Text Generator Type shows Advanced, yet warnings still reference the Standard TextGenerator when Auto Size is use.
