OpenGL Shaders Spam

[3lyrion]

14:40:53: Vertex Shader: 100000038VertexShader_vs
Fragment Shader: 100000038PixelShader_ps
 GLSL validation result : 
the set of active program objects contains two active samplers of different types, but refer to the same texture image unit
14:40:53: Vertex Shader: 100000039VertexShader_vs
Fragment Shader: 100000039PixelShader_ps

Why do these messages appear in the samples? I also get a lot of shader files in the working directory
