OpenGL Texture - texture render twice - c++

Question

I have a problem that a texture covers only part of an object in height dimensions and start over again rendering a smaller texture in the bottom as shown in the pic.
I'm posting my Texture and Shader code as well. note that I'm using glTexSubImage2D for the background of the object. the same problem occurred when I didn't use the glTexSubImage2D and just glTexImage2D.
texture code
try {
data = stbi_load((fileName).c_str(), &width, &height, &numComponents, 4);
if (data == NULL)
std::cerr << "Unable to load texture: " << fileName << std::endl;
else
std::cerr << "texture loaded " << fileName << std::endl;
std::string fileName2 = t ? filePathe + "//images//" + mediaColor + ".bmp" : "./res/textures/plane1.bmp";
int width2, height2, numComponents2;
unsigned char* data2 = stbi_load((fileName2).c_str(), &width2, &height2, &numComponents2, 4);
if (data2 == NULL)
std::cerr << "Unable to load texture: " << fileName2 << std::endl;
else
std::cerr << "texture loaded " << fileName2 << std::endl;
glGenTextures(1, &m_texture);
glBindTexture(GL_TEXTURE_2D, m_texture);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_REPEAT);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_REPEAT);
glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR);
glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR);
glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, width2, height2, 0, GL_RGBA, GL_UNSIGNED_BYTE, data2);
glTexSubImage2D(GL_TEXTURE_2D, 0, 0, 0, width, height , GL_RGBA, GL_UNSIGNED_BYTE, data);
stbi_image_free(data);
stbi_image_free(data2);
}
