TFC 1.18.2-2.2.30

There is an odd thing that show when the hammer icon "hit any" show in the instruction.

it seems to be this greyscale scroll in the texture

Used color to define the zone for each icons.
Green is the hammer, blue the scroll, yellow is the overlap. Red was just to check the size.

So yes it's a texture problem, but also need to be fixed in the code to take different sections of the texture.

Fixed in 1.20, given it's a minor texture error and can't be fixed without breaking existing texture packs (in which case is a "who breaks") not fixing for 1.18.
