My WP theme got rejected for 4th time. Pls help.

Hi All,
i’m confused as my wordpress theme is rejected for 4th time.
Pls advise what can be my issues and what to improve or what are my errors.
Thank you
P.S. I have correct spacing, improve design, fix RevSlider and added dark version.

Not sure if this is the reason, but this is how it looks like when I clicked the demo for the first time (the second time is displayed fine):

Later edit: and I’m on a 1Gbps LAN connection, so loading CSS is not the problem.

Thank you Hevada, i saw the same just one time for 8 months, it was when my style was not fully loaded due to internet interruption just for second. Actuall i no have Soft reject, hope this is better.
