is this Jungle Val or Dwarf Sag?

A while back, I bought some of these plants and trimmed the dead leaves. When I planted it, I planted them rather deep and the crown was under the substrate, and as a result they slowly started to die. I redid my tank and leaned I had to keep the crown above the substrate. Well a few months later they have recovered pretty well. Only problem is I could have sworn that when I bought these plants they were jungle vals but now they are looking like dwarf sag. I did have some dwarf sag in my tank to and it is possible that I got them mixed up but I don't think that is the case. It has been about 3 months since and redid the tank and they are spreading like crazy. They are just not growing tall. Is this common for jungle val to stay short. I do have med to med-high light.

Thanks.
