Cannot Purchases Any More Pages In The Bank

Hello everyone! I noticed that I could not buy more pages in the enderchest of the bank. Whenever I try to do this, it plays a sound as if I successfully bought it, without giving me access to the additional page. I am trying to buy page number 4. I am already level 31 and I have enough emeralds. Does anyone know how to fix this? or anyone who has the same issue as me? Please share your thoughts :)

 

Are you using any game modifications? If so, disable them and then try purchasing the page again. Additionally, make sure to use Minecraft 1.12.2 if you are not already, as it is guaranteed to basically not have bugs like this.

 

I do believe wynntils causes this, theres an option in wynntils that you can toggle off so you dont have bank page confirmations

 

Thank you for your replies! I do use game modifications however it does not seem to affect the bank as my friend uses the same modifications. Bax's reply helped me. Thank you so much!
