Please use one topic for only one question.
the fact is that if i disable the yellow pencil, the modifications pass away e.g the shadow on the boxes https://snag.gy/Zv9VcH.jpg
without yellow pencil enabled this is what appears https://snag.gy/HB7vsa.jpg ……for example.
and generally many modifications are lost without it.so what must be done please?
