Can someone tell me why?

Are you using a texture pack? Although as mentioned in #56, there are still some issues on larger resolution screens after I changed some code.

Any update on this? If you still have the issue could you try 0.0.17.75?

Just had a similar issue on a texture pack. Note to make here is that the boxes in the texture sheet need to be full width of the sheet. See in https://github.com/way2muchnoise/BetterAdvancements/blob/master/src/main/resources/assets/betteradvancements/textures/gui/widgets.png
