equipment tends to get switched around when you move different team members in and out of the 4 "battle" slots.

for example during 9tails world boss when you make your 9tails team they get the equipments all mixed up so when you switch back after event the equipment is re-arranged

options:
*level all gear equally
*dont switch your main 4 ninjas once you have them the way you want
*deal with the mix ups during ninja swaps and re-arrange accordingly
