My collection is gone! [opgelost]

I had over 500 items and now it says I have like 30 items. What do I do? Who do I talk to? 

Most often it's filter settings. 

From your profile you have probably have set it to tokens or banknotes of which you claim to own 35 and 39 (your collection contains 550 items).

That was what happened lol. I was freaking out since I spent soo much time inputting everything. That’s not even half my collection but little by little I’ll add everything. Thank you for the reply. I’m still learning how everything works on here.
