Tag historian binding now has 2 rows

I have a tag historian binding of 71 columns.

I edited a few values in it.
Now it has a second row and it is not supposed to.
Version 8.1.0
Is there a solution to remove the second row?

Screenshot and show the binding configuration.

Every image upload says error. I tried png and jpeg.

I have wide, point count 1, realtime 1 minute most recent, 30 secon polling

71 direct tags selected, min/max aggregate.

options enabled, format dataset

preview says dataset[2 rows, 71 cols]

I switched to last value, and it seems to be working. I am not sure what happened.
I think it was always set for default, and min/max while it only had one value.
