Power Platform Community Forum Thread Details

Body:

Environment: Dynamics 365 / Dataverse, model-driven app, managed solution deployed via Azure DevOps (Power Platform Build Tools, Import Solution task v2 / pac CLI).

Problem:

In one specific environment (DEV), a main form renders every tab as the literal fallback text "Tab" ("Tab Tab Tab") instead of the authored labels (General / Notes / Administration). Sections are similarly unlabeled.

What I've verified so far:

The artifact is clean. I extracted the managed solution zip and inspected the form XML in customizations.xml directly. The form (same formid across all environments) contains all tab and section labels at languagecode 1033 (e.g., <label description="General" languagecode="1033" />).

The same artifact renders correctly in other environments. A sibling DEV environment and PROD, with the same solution at the same or lower version, render all labels correctly.

The layer in the broken environment has no labels. Comparing the form's Solution Layers in a working environment vs the broken one: in the working env, the solution layer's Properties pane shows a "Localized Labels" tab listing all labels at 1033. In the broken env, the same layer for the same formid has no Localized Labels tab at all — the formjson structure (Tabs/Sections/Rows) is intact, but label strings are absent.

No unmanaged/active layer is present on the form in the broken environment — single managed layer only.

Re-import with force-overwrite does not fix it. Re-imported the verified-clean managed zip via pipeline; pac CLI log confirms --force-overwrite true --publish-changes true. Import completes with Success. The layer still has no localized labels afterward.
