acszsolti After exporting my animation from Spine and import in Unity some frames appear different in game mode
I assume that you mean that there is the inside (back-face) of the "7" visible (on top), which should not be visible. It was a bit hard to notice at first since the screenshots are quite different, having completely different pose and background. Please always describe or highlight the exact difference to save us some time searching.
Did you enable backface culling in the Spine Editor settings? If so, you need to copy your used shader in Unity and disable backface culling there by changing (commenting out) all occurrances of the line from
// Cull Off
If you have backface culling disabled in the Spine Editor, your draw order might be the problem.
