Mods studio 2020 (Euro Truck Simulator 2)

Hello everyone! Guys, help me figure out the problem. When loading a dds file into the ETS Mods Studio 2 program and trying to convert it to scs, the program gives an error "Dimensions is not in power two". I looked on the Internet, it says that the width and height of the file must be a multiple of two. I looked at myself - 4096x4096 resolution 512 and this error still pops up. Who is in the subject, tell me what to do, how to fix it?
