Dr Weightmans pharmacy - second order of 7.2mg and got sentt the american style auto injector single use pens

I have ordered 7.2mg from Drweightmans pharmacy before and got the usual 3x 2.4mg pens. This time I got the american style auo injector ones. 7.2mg is too strong for me so I count clicks to take 4mgs. Has anyone else experienced this problem?
