Chance for reconsideration of visa application, I-129S is stamped 'Not Clearly Approvable' without any slip/paper

I attained the L1-A Blanket interview on 03-Aug-2017. Officer stamped ‘Not Clearly Approvable’ and returned two copies of I-129S, I-769 and DS-160 without any slip/paper. Currently, it is showing the status ‘Administrative Processing’ on CEAC site. Does it mean that it is rejected, or they are going to check it again and I might be asked for any evidence? In simple, is there any chance for reconsidering this case?

Not clearly approvable means a clear relationship between you and employer is not evident based on papers submitted. You are in admin processing and evidence will be requested soon.

Is there any update after this? did they asked for any documents?
