Issues with button rendering and Textures

[IsLegitimate]

The canvas tool buttons aren't updating there toggle state from on, selected and off... Also I was trying to make a resource pack to texture them with a sleek easel color. I noticed that even when you make a resource pack folder that sources the asset>zetter>gui> (.pngs) it doesn't update or override the texture in the pack. Also found while changing the (.pngs) there is a light gray box that overlays the "8) Current tab" space (above where you have the inventory slots covered. I can't seem to find where it's sourcing this light grey color from as it's not in (easel.png), (widgets.png). Maybe it is but I'm not sure would appreciate help. I'll send you the textures if you want to add the to the game. They are pretty vanilla... themed to Colorful Containers GUI Resource Pack
