Is my Frankenstein mushroom splitting

[Rick's Reviews]

Hi, I have various mushroom spieces which all are doing great (collector not seller)
I purchased this Frankenstein a couple of months ago, it's still on the bigger frag plug/ not standard 22mm (maybe 25mm-28) and it seems to be folding in half?
I have seem my other mushrooms split which is basically them ripping themselves in half, however this is first time I have seen this kind of fold

Is this normal for a Frankenstein please??

Thanks
