Frogspawn pinching a new head?

[HiImSean]

When I picked up this frogspawn it was one big head as seen below

Since I've purchased it, the tissue has recessed from over the head and it looks as though the skeleton is pinching together and forming 2-3 heads total. It still has good polyp extensions and I can see 2-3 mouths. At night it retracts a little and you can see tissue/skeleton where its pinching together. Is this normal? I thought that they usually bud new heads? The only other frogspawn I've owned was purchased as two large heads with similar skeleton structure to this one. I will try to get a better picture of where it's coming together tonight. Since it started doing this I moved it to a lower flow spot in my tank and I think it's be going on for a good 3 weeks now.

For the torch and hammer I have, it's usually a bud on the skeleton or a bubble over one of the mouths. I have not seen what you are referring to. Make sure it is not brown jelly.

This bad:

This is good, although when i posted this it was receding but you get the hint:

Bubble:
