Chaos AR Defense… glitch?

So I was getting ready to do my AR-O set ups and checked on my defense records.

Seems normal.

Then I opened the bottom replay:

Why are there only 4 units?

Replay 2:

0 changes to the map, just made a specific map now for chaos. Why is there only 4 units in the first battle? My first offense map had 6 units, so it’s not like everyone’s first battle was on super easy. In addition, my fort was level 1, when it should be level 5. I made zero updates until NOW so I didn’t have the bonus structure, the same team was present and locked, but why does the first replay only have 4 units?
