In iOS 14.2, 10keys Japanese keyboard not working or not convert into default QWERTY keyboard for secure textfields.

Let me describe my problem briefly:

First of all, my device language is Japanese. Now in my existing application's signup screen, i have 4 textfields. And among them last 2 are secure textfields. Also, all textfields keyboard type is set to default.
Now, i have started editing from 1st textfield (which is not secure). Here, i get default QWERTY keyboard. Now, i am going to change this keyboard language by pressing language icon(world icon) from bottom left and convert this keyboard to 10 keys Japanese keyboard. Here, this keyboard is working properly. Even i can long press on any key to select other characters from it.
But, after this textfield editing finish, i have started editing in secure textfield. But, here:
  • I can get 10 keys Japanese keyboard not default. (In iOS 12, 13, 14.0. It converts to default QWERTY keyboard)

  • No language icon at bottom left to change keyboard.

  • Even 10key Japanese keyboard, not able to select 2nd character from key. (Long press not working. Only first character is selectable.)

Is there any one has idea about this?
I have the same issue, I solved it by rename Sign Up View Controller to another name like 'SUpViewController', then everything works properly. May be IOS recognizes view controller name to help app suggest password but because of the weird reason, it caused bug in keyboard
