gallery app not organizing by file name

[theanghellicone]

i'm one of those ocd types that organzie all pictures and put them all by name. and that's how i want to view them....

so today i decide to load up all the pictures taken from the walking dead escape the other weak.

and notice that the pictures are just randomly thrown about in the gallery.

the settigns only let me group them. that's not what i want. i want them to go from alphatical order!!! anyone else have this issue?
