Led panel color off

Hi video lads! The company I work for recently purchased some panels that are running A10pros receiving cards, running novastar vx16s processors, and novalct software. We’ve been having some issues with some of the panels being a slightly off color than the rest of the panels. We’ve tried running the rcfg file through them and that doesn’t seem to work. We swapped the module on the back of them and the color fixed after that. Is this a receiving card issue or are we doing something wrong?

Sincerely,
