Hello and sorry for getting back to you so late.

What are you SharePoint and QuickApps versions?

Please try to simplify the grouping in the qListView for testing purposes and see whether the aggregation number is correct. From the screenshot I see that there are 6 items under the first user and this is how this gets reported. I don't think that multiple aggregations can be done, can you please attach a test list and the web part template so I can try it?

Regarding the alignment, you can try to customize the aggregation row spacing and achieve the proper alignment.

Let me know how it goes please.
