Seams lost while using Atlas tool

Support Materials and Textures

Hello, I did search but I cannot find the answer anywhere.

I need to put multiple objects to one UV map. Atlas tool allows me do just that the only problem is that all seams I did in those models are gone (after selecting StartManualUnwrap). I cannot afford to re-seam the model because it would be a huge time waste. Am I missing something? Thank you in advance.

They are there, just not visible for some reason. Enable seams visibility from 3d view properties -> mesh display.

Thanks! I have no idea how I missed it since I turn edge length and normal quite often in the same panel.
