Please check following:

1. Use Page List as Data Source

Ensure your repeating dynamic layout is bound to a Page List structure. This allows each row to maintain its own data context, including its own signature field.

2. Configure Signature Field Correctly

Each signature capture control must reference a property within the Page List item, not a top-level property. 

3. Avoid Shared Controls

Do not reuse the same section or control instance across rows unless it's properly parameterized. 

Use autogenerated sections and ensure the signature control is embedded within the row-specific context.

4. Check Layout Configuration

Repeating dynamic layouts using page groups do not support CRUD operations 

Use defer load and visibility conditions to optimize rendering and avoid shared state issues.
