HELP! Botm Adult Triceratops head won’t stay in!

[Pliosaurking]

Hello everyone, I was wondering if anyone has had this happen/tips to fix this?
The head on my trike won't stay in no matter how hard I push it, it won't stay in. The only way it stays in is when the head is positioned to be looking either side. Between this and having the odd number of horns I've had quite a few hiccups with this one, which sucks as it's such a good figure. If anyone knows how to solve this please let me know! I might just end up having to contact David about this..

Definitely reach out to David. He's helped me a plenty to fix things up.
