Actually these issues had been existed for years I'm just lazy to report it. My character uses 3 blue candles and here are the bugs: 1 If double click a pet equip (e.g. item pouch) then choose a candle pet pressing OK, it won't work, I can only equip that via opening equip window then single click/drag, this issue exists on other color of candles too, not sure about other pets but have not found any so far. 2 When double clicking my character, my pet equip still not display correctly, this issue tagged fixed since last time I reported it but not really fixed, for my character's case it only shows 2 green pumpkin kids, I actually equipped 3.
Have you summoned your pets by selecting 'Cancel' when being prompted about whether to change Lead Pet?
Upon selecting 'Yes', the pets will be bugged such as pets being un-summoned upon changing channel, 2nd and 3rd equips will not work, or pet equips stats does not reflect Hence the confirmation of the selection Based on your description of the issue, maybe it only occurs for this particular pet's equip
