The ledger entry format is brand name at the top of the page, an item from that brand, then directly next to it and inline with the top of that item the information begins.
Take a look at some of the entries:

The 3/17/1910 date is exactly where it should be as a description next to the coupon that coincides with T210. The same for the discontinued date. It is not near the above T206 references at all, there is a very clear space and it was intentionally written directly next to the T210 related coupon. Then the cabinet entry is directly below the coupon for that specific cabinet.
We just aren't seeing the same ledger.
