What does "Not Fitting" mean? Not long enough? Too wide for the chain ring? Too short to go around 50t? Too long to go around 34t? Links too wide to sit on the FW or the chainrings? The chain is too tight or too loose when running fixed gear? The chain alignment is off? Or some other description is necessary to understand your problem.

An 1/8" wide chain is just for single speed/IGH drive trains, these days.

You pick the chain by how many cogs are on the back hub..
5~8 is one width, 9 & 10 each have their own

you need a 3/32" freewheel if you use 2 chainrings, not an 1/8" thick one.
that is if you run a single in the back..
