The problem is already explained in depth in this thread! Sorry, but I don’t know how to explain it more in depth!
I had already posted screen/resolution/browser above!
I apologize for my fuzzyness. I have literally lost the track of all details.
Yes, aparently this is a bug which needs to be fixed. Thank you for noticing us about it.
As a temporary fix, please change the files display type from current one to block style by pressing the button with 4 squares from the top right corner of the screen, and try again.
If the problem persists, please notice us about it and expect for a fix to come up soon. We are sorry for inconvenience
