Why do I have a difference between retained earnings and all earnings

Why do I have a difference between retained earnings and all earnings, aren’t they supposed to be equal?

Please set language to English before you make a screenshot, so you have more chance your question can be answered.
So, as far as I can see:

  • on bottom the left side you see the retained earnings of the period used for this summary.
  • on the right side the retained earnings made until the second date used for this summary.

No, they are not. You should refer to basic accounting references.
