i tried connecting the brown and blue from the wardrobe in terms 1 and 6 to see if i could just use the bedroom switch for both lights and the same happens, wardrobe works and the bedroom doesn't
Thats not true, from the info you've given terms 1+2 (switched live) are the same as are 5+6 (neutral). You previously said that when connected to terms 2+5 both lights came on together, therefore the same will happen when connected to 1+6.
Get an spark to sort it out and test your circuits - its very dangerous.
