Issue Creating a New TV Episode

Hi I am currently in the process of correcting episode numbers of the TV series Emmerdale Farm - tt0068069. There are various issues with episode numbers being allocated to incorrect episodes, etc. but most I am able to amend, albeit by first deleting the incorrect numbers to avoid unwanted merges. Episode number 1.5531 was a duplicate of episode 1.5525 in all but number, so 1.5531 was amended to 1.5525 and the two successfully merged - or so I thought. However, when I attempt to create a new episode 1.5531 I get the message that the episode number already exists, although it doesn’t show up anywhere. When clicking on the link it takes me to episode 1.5525. The only way to create ep 1.5531 is by accepting the merge, but this just seems to again merge into 1.5225 - which now shows the incorrect release date (the date of ep 1.5531). It seems there has been an error made or a glitch in the system when 1.5531 and 1.5225 were initially merged. Can this be looked into please? Perhaps the best solution is to delete the existing episode 1.5525 then hopefully both episodes can be successfully created again. Current Episode 1.5525: tt1596430 Original merge request: 241030-091527-772000 Attempt to create 1.5531: 241101-150524-744000 Many thanks CaptainSiCo
