My idea was missing in ideas section

Hi,

I’ve add an idea in the ideas link on top a few weeks back, it’s gone when I try to find it today, I’ve around 50 over votes and now it’s missing, original link is here

https://ideas.premiumpress.com/idea/separating-category-and-sub-category/

Please kindly advise, I’ve press so hard for this features and got a few who also voted for this idea also and now it’s gone when I try to go back to vote today, I couldn’t find it anymore, it should be at page 4/5, but I screen through the whole ideas section but just couldn’t find it.

Please kindly advise and get it back, thank you.
