Looking at your photos one can see clearly there is at least a portion of unthreaded area of the hub inside the spinner. On mine that is quite wide ( I will have to go out to the shop & measure to be exact ) if yours is the same you do not have enough thread holding the spinner on.

Went out & measured---3/4" protruding out of spinner.
1/2" unthreaded starter nipple--approx 2 threds=1/4" Total--3/4"

So if yours are manufactured the same, you do not have proper thread engagememt

I think Craig might be right. Here's a shot of mine for a comparison.
