EncoderLayer & Encoder Wrong Values

Hi, it is so frustrating that none of the coaches has helped me so far. I invested a lot of time and read all the comments regarding similar issues, I also checked my code and there is nothing I can find but I am still getting wrong values and the course ends on Monday.
@coaches: I do not know how to share my notebook with you correctly. So, it is very nice to suggest for me to share it with you, but pls explain how. I tried but I do not know if I did it correctly, since nobody answered.
So pls help me with this issue till Monday noon CET - ca. after that time the course is over.

See my response on your other thread.
