Inconsistent behaviour populating Word template from Microsoft List via Power Automate

I'm using a Premium Power Automate and using a series of flows to manage an approval process and populate a Word template from a Microsoft List using content controls at each stage of approval. Approval occurs at several stages in a workflow and, in most cases, works correctly.

However, I have two issues occurring at specific points in the process, despite the flows, mappings, list columns and content controls being configured identically to other stages that work correctly.

Issue 1 - Field not populating Word template

• Data entered into the Microsoft List is present and saved correctly.
• One specific field (Q1) fails to populate its corresponding content control in the Word template, leaving it blank.
• Other fields populate correctly.
• The same field and content control setup works correctly at other stages of the process.

Issue 2 - Field reverting to previous value

• A different field (Q2) behaves unexpectedly when an amendment is made in the Microsoft List.
• The user updates the field and saves the item successfully.
• The updated value is visible in the list.
• When the flow triggers, this specific field reverts back to its previous value and the Word template is populated with the old information.
• All other fields retain their updated values.
• This only occurs at one or two stages of the process. Elsewhere, the same setup works as expected.

Troubleshooting already completed

• Confirmed the data exists in the Microsoft List.
• Checked list column settings and data types.
• Checked Word template content controls.
• Deleted and recreated the affected actions.
• Copied actions from working flows and also rebuilt them from scratch.
• Reviewed dynamic content mappings.
• Exhausted all troubleshooting steps suggested by Copilot.

Has anyone experienced fields intermittently failing to populate Word content controls, or list column values reverting to a previous value when a flow runs? Any guidance on what else I should investigate would be appreciated.
