Greetings from Com2uS!
Please read below for detailed information on an error that's being experienced on iOS devices.
[Equipment Material Display Error]
We've confirmed an error where the previously selected material equipment being remained even if you change the target equipment for power-up after selecting the target equipment and material equipment.
Please note that this is only a display error and you won't be able to proceed with the power-up unless you select the material equipment additionally because, in this case, it is considered that there's no material equipment selected to perform the power-up.
(If you encounter the same error, please move to the main page and go back to the power-up page to resolve the issue.)
Therefore, please make sure to select the material equipment again if you decide to change the target equipment even though the previously selected material equipment is displayed in the UI.
(Only material equipment selected additionally will be used for the power-up.)
Once again, please keep this situation in mind when you perform an equipment power-up and this issue will be resolved via an update in future.
We sincerely apologize for the inconvenience caused by this issue and thank you for your understanding.
