GTC Listed item not showing in my ebay store

[plaig_bearings]

Hi,

I have been selling on ebay for a very long time and never had this type of issue before, It is in regards to this item:

http://www.ebay.com.au/itm/5x10x3mm-Open-RC-Bearings-10-Unshielded-Plaig-Bearings-MR105-/15141702725...

When I search for the item using any keywords it does not show up in my ebay store, and it is not listed in any categories. I noticed this several days ago but it seemed to fix itself the next day, I just checked again and its now doing it again, does anybody have any suggestions? I don't want to go through all my listings and see what else isn't coming up but I know of one other that is doing the same. Here is my store:

Any help would be greatly appreciated. Thanks
