Table.Buffer - Still not sorting|Power Query|Excel Forum|My Online Training Hub

I have a PQ which is attempting to sort two columns, one by date, one by time. When loading the query into a table, the order is not in the desired order I set in PQ.

I did a bit of research, and learnt that wrapping sort with Table.Buffer usually resolves this, so I created this.

In preview mode, it lists the data in perfect order.

However, when the data is loaded to a table, the table does not duplicate the above, skipping dates and times.

It's sorting in a manner, but missing many many rows and sorting them further down the table. For instance, 14/04/2022 is on the 20,000th row.

I did some further investigation, and referenced my original query without any additional steps. Loading the referenced query, displays the table perfectly! I'm completely confused as to how the original query is not sorting how I want it, but referencing it does.

Any thoughts?
