Fixed the issue, turns out that out of the three strings OP said need to be added:
- First one was already present.
- You only add the second/third one depending on your image you will use, e.g. if you choose to name the image "semc_bg_tile" then you only need the string mentioning "semc_bg_tile" and same applies for the other ("semc_bg_bright_tile") string. Credit: MahaDEVELOPER
