Texture glitch in creative menu [MCPE] (SOLVED)

There is a glitch in the textures for the tabs shown in the creative mode menu, affecting all tabs except for the "All" and "Construction" tab.

Basically speaking, on the top there are 3 extra white pixels, and on the bottom every tab is glitched over the menu.

These 2 screenshots will hopefully help.

(Update: Neverminf, the bug was from an addon. Nothing to fix here.)
