[Investigating] Upgrading item bug

After selecting my royal armour to upgrade this is the screen I get. If I tap where the level 49 upgrade box should be, nothing happens. If I tap on the level 50 upgrade box the level 49 upgrade box appears and I can then select it.


Restarting game/phone makes no difference.
If I do the above to get the level 49 box to show as soon as I close the upgrade window and open it again the level 49 box is missing again.
Running latest version of PQ3 on android 10. Just for fun I opened my game in steam and the bug does not occur.
