No Sample Requests are "found" in v12 ASM Traffic Learning

Hello Erik, The part of them do not appear , there are logs in traffic learning but not all, I could not say that I do not get any request. for example :0 sample requests out of 74 that triggered the suggestion from 2017-07-03 17:29:41 until 2017-08-31 15:12:29 , and "No samples found in requests list" is shown in the traffic learning windows. The only reason I am thinking of is local storage is not capable to keep all those logs and it clears when it reaches 2 GB.
