I'm not sure where frame 24 is. Could you give the posting number? It's in the upper-right corner of the posting. For example, this is posting #521.

BTW, having XTOL last 4 years is amazing. You mention keeping it chilled: Do you have issues with precipitate collecting at the bottom of the bottle? When I tried refrigerating my XTOL, I quickly got some precipitation.
