Why Doesn't Same Price/Type in TOS Match Cummulative Last Traded Size in DOM?

Just trying to find out why what I'm seeing for Cummulative Last Size in the DOM doesn't show up in Time and Sales as the same size when Same Price/Type is being used.

These should match since they are basically the same thing, correct?

When observing this, you can clearly see 20 contracts or more going off at bid/ask in DOM but these trades register as 1-2 lot individual trades in TOS.

What am I missing?

There are implementation differences. There is no consideration to whether a trade occurs at the bid or ask with Cumulative Last Size.
