Bug - bank1 does not exist and bank24 is the second to last bank slot

[PricklyGoat723]

If I open the first bag in my bank, top left corner of the first section, and type:
/echo ${Window[bank1].Text}
then i get NULL
but if i type /echo ${Window[bank2].Text}
then i get Tan Battleworn Sack
but its in the first bank slot not the second.
I have a similar problem at the end, /echo ${Window[bank24].Text} shows my 2nd to last bag, and of course /echo ${Window[bank25].Text} returns NULL.
