Array Formula Not Expanding To Match Lines Added To Table?

I have a number of array formulas that refer back to the table in the top left. The array formulas are in Columns I and L, and cells N200, N203, and P203.

Normally when I add a new line to the top left table (usually by clicking on the empty box below the previous final line and typing the date), the table expands by one row and the array formulas all adjust to match, i.e. all the A180/C180s in the formulas become A181/C181s, etc.

However every once in a while (maybe once a month), the arrays simply refuse to update, and I can't figure out why. When they fail, they all fail, it's not hit or miss. You'll see in the attached sheet that though I've added a line to the table (A181) and data to that line, all the arrays still read through A180/C180.

Why this randomly fails to update, and if it's something I'm doing incorrectly?

And that leads to an associated question. In the past when this has failed in this manner, I've laboriously gone through and changed all the cell references manually, in every single individual cell. (After doing it once, the arrays usually magically start auto-expanding again.) I'm certain there is a way to make those formulas refer to a named range, instead of all being manual references, but after spending an hour on it, I keep getting #VALUE errors.

I've been using [URL] ..... and pages like it as a reference without success. Obviously, I would prefer that the formulas auto-update without issue per my first issue above, but in the event that they don't, it'd be really nice to just change the ranges in one location and have that propagate across the sheet.
