Looks like the heads of the bolts are smaller than the holes. Possibly the result of rounding off. Maybe a larger washer under the heads is what's called for. Likewise on the back of the flange nut on the inner. Note that the inner's holes may be counter-bored on one side. If so, that goes toward the frame, so the flange nut's head pockets into it.
The correct sequence is flange nut, inner ring (recessed side to the head), crank arm, outer, washer, bolt. BTW- where's the 3rd flange nut. You absolutely need 3 to hold it on.
