Filter Duplicates based on other column being blank

This is a further but distinct issue to this thread

https://community.powerbi.com/t5/Desktop/Aggregate-Timesheets-by-week-to-compare-against-scheduled-hours/m-p/3180849#M1072751

I applied the steps, but have found that;

Merge Queries imported the records but it would then fail to populate the Resourcing Hours column if the Actual Hours column was blank. 

Merge Queries1 imported the Resourcing hours, but also has caused duplications - see below with the indexes (which I added in so that I could measure if it was duplicating)

I have sought to map as many columns as possible when doing Merge Queries, but it still duplicates and adds in these blank rows. 

What i need is a way to query Resourcing.Index to find its duplicate BUT remove the duplicate which lacks records the 2.Index Column. 
Suggestions Please? Should I add a binary column to measure if Index is blank?
