• The indentation for the new - actions: [import] entry is inconsistent with surrounding entries; it should match the existing 6-space indent to ensure valid YAML.

    - actions: [import]

env/includes/settings/tk-multi-shotgunpanel.yml:335

• This actions line is indented differently than the filters line below; align it to the same indent level as its peer entries for proper parsing.

    - actions: [import_front_sceneplate, import_back_sceneplate]

env/includes/settings/tk-multi-loader2.yml:400

• Indentation for the Image key should match surrounding file-type mappings (e.g., 6 spaces) to maintain valid YAML structure.

• The Rendered Image mapping is misaligned compared to its peers; please adjust the indent to match other file-type entries.
