Mosaicking tool causes a spatial shift

Dear SNAP community!

Currently, I am mosaicking two spatially overlapping S2L2A scenes as seen below:

One image is in grey color scale while another one is in color. As it can be seen pixels are located correctly. However, after mosaicking (the mosaic is in color) I observed a shift compared to the original scene (in grey) as shown in the figure below:

Here are the parameters I have used using SNAP GUI:

I would be happy if you could help me with that issue.
