On order quantities linger after an upgrade

SOLVED

.  The client is noticing quite a lot of this. This is from the IC location details screen Sage 300 2020 Perpetual license.

The screen shows 10 on hand 44 on sales order.  However, 44 are not on sales order.  There are only 24 total on sales order.  

I suspect a relic from data conversion. How do I fix this type of thing? Does Data Integrity fix this? 

(I know how to do it in Sage Pro, but not in Sage 300). 

Thanks,
