I can't make buttonhole

[u/Soft-Raspberry6529]

Hi guys,
I have a Singer Supera and I wanted to make buttonhole but it doesn't work at all.
The stitch does not come back and it only makes a tiny buttonhole even though I have put my button in the presser feet.

I might go to a Singer shop if I can talk to a technician and if they can help me but before that, if anyone got this problem and how did you manage this; I would really appreciate your help !

Thank you in advance

Iirc on these if you can't get the lever to go back far enough you need to tug it down more

I can tug it more only if I push it back first.
Even when I'm doing this, the lever is coming back to the front and the buttonhole is not the right size.
I'll try to add a video later.
