UK Catalogue - order problems

I am sure that you are implementing a new feature or something but the UK coin section of the catalogue now has duplication in the coin types also the coin order is messed up as well.

Can you make a screen shot? Or on which pages is there a problem?

At first sight I don't see anything odd here.

should be able to right click and open in new tab or save file to see the full page, displaying 100 items made the file bigger than the 8mb allowed for the forum.

I don't see any duplication in your picture but the order is indeed a mess. Check your display options and see if these are still the same as before.

I've been working on amendments all morning and just pressed refresh, has the by reference display option always been there as that seems to be what is causing the mess...

I noticed your order is now by reference. I don't know exactly when that option is implemented but for sure already for quite some time.
Are you perhaps using another browser now? I had the same problem after using another browser (not the duplication but the messed order), that's why I knew you probably had a problem with your display options. I guess it's back all right now?

Same browser same everything, not sure why when i pressed f5 it reverted to by reference, back to as i expected it now.

The standard sorting is done by 'face value' but the real problem here is Spink's numbering system using letters in front instead of continuing to use just numbers.
The ordering option is here since before I made my account and if you click on a search query link in the forum you will take over the settings of this search. This is the reason many people cry "I can't find any coins anymore" and they have ticked only non circulating issues from a previous search query link.
