Searching for Ticketmaster Resale Tickets

I've been looking our for resale tickets for weekend camping to Rewind festival north for a week or so but nothing has come up when I search. This is what I see -
https://www.ticketmaster.co.uk/event/36005B2FDD3E4919

...which just shows me regular priced tickets at £140

But someone on facebook has put some tickets on sale a week ago -

These have definitely not come up in any search I have made, is there some way I should be searching for these?
