Problem when exporting maps

Hello, the program is the same, the settings are all the same, on the 1st screenshot the model was textured from 0 and then transferred via smart materials or via cards to the same version of sp with settings 1:1, in addition to the fact that the spots started to look different (this is not the main thing), the ambient occlusion channel with the L8 setting It does not transfer or save any information.
As a result, in the same joint venture and other programs, the model is lighter.

Is there any way to save (export) the model so that it stores information in dark shades? In the future, when I open a model, I want to see it the same as I saved it, and in the same SP, with the exact same settings and even the same layers, it becomes lighter, but if I manually add AO L8, it will be ideal, but you can't configure these options in marmoset toolbag. so I want to see the final result immediately when exporting.

I tried to access the channel profile in the settings themselves, tried to save the ao in other channels during export, nothing changes.
