Main site glitch/hidden pub

[sheffield hatter]

While out for a walk yesterday I came across a pub I hadn't seen before, the New Inn on Carbrook Street in Attercliffe. It had clearly been closed for a long time and appears to be in other use, possibly as offices for one of the nearby businesses. I took a photo, intending to add it to the site. However, I could find no such pub on the Sheffield list. I therefore did a Google search and found an entry on WhatPub, copied the postcode and created a new entry in Pubs Galore. At this point, a match was found to this existing entry: New Inn.

The pub had been added to the area Carbrook back in 2012 by me, but on checking the Carbrook area there was no sign of the pub. I decided to try adding the pub to Attercliffe as well, but afterwards, on checking the Attercliffe area, there was again no sign of the pub. It appears to be "hidden", and in fact the only way I could find it again was to once more create a new entry and wait for the original to be flagged up. (The postcode on WhatPub is incorrect - it should be S9 2JN, as on the PuG entry.)

Can anyone suggest what is going on here?

PS I have since added my photo, and it appears on the Carbrook page under New Carbrook pub pictures, but the pub is still not listed!
