The Super Ikonta III and IV will often have tight or slightly overlapping frames, even when loaded right. You can either advance the film a little further passed the start marks before closing the back, or "pad" the take-up spool out with a couple of turns of old backing paper.

The start marks line up with the counter reset on the right, about 1 cm in from the right hand film roller (take-up side).

Hope this helps.
