Having trouble with flipbook animation tiling incorrectly in Shader Graph

I’m trying to create a fire effect using a 16x4 flipbook texture in Unity’s Shader Graph, but I’m running into an issue — the image seems to tile horizontally (U direction) instead of animating properly through the frames.

I’m using Shader Graph, not code.
If anyone has a step-by-step or node-based setup** for flipbook animations like this, I’d really appreciate it!
