Next to me cot and mattress (Nuneaton CV10)

One screw does not screw in properly, don’t think it’s the correct screw. Cant seem to dismantle the cot for transport as the sides are clipped in well and I don’t want to break the cot but doesn’t affect the use of the cot. Will fit in a car if the seats are down. Used for 6 months with no issues.
