This is not a bug. This bar was removed because it had no meaning. Labs are advancing research progress in a continuous way and there was absolutely nothing happening when productivity progress bar was full. You may also notice the normal crafting bar is also gone as it was also meaningless, there is only overall technology research progress visible.
