Custom data table result search duplicates results

Hello,

I've created a custom search to find documents belonging to a custom doctype. When the query is initialized, all results are doubled. But when I clear and relunch the search, it's working correctly.

• The NXQL questy is correct and checked
• Cannot be reproduced with default search, nor expired, no asset search
