Help! Grey spots on white marble flooring

Help! We are installing 36x36 white marble tile (Everest Blanco Polished) on floors. We sealed the underside of each tile with Fila Pre-Installation Efflorescence Protector and using Amerimix Masonry Cement & Sand mortar. The tiles looked fine when being installed but within 15 hours there were random grey spots throughout the tiles. The installers think that it is water vapor that will eventually dry and return the stone to it's original white color. I stopped the installation to see if this happens as this material was not cheap. It's been two days and I think I'm seeing some improvement but not sure. Has anyone else had this happen? Do you really think it is trapped water vapors? Help please!
