Kaltura11.14 - RemoteStorage - Problems with Thumbnails

I have installed a Kaltura 11.14. I use Remote Storage for publishers because it is the only way to operate the delivery profiles with Wowza server. Video encodings are removed from local storage and stored in the Remote Storage. I have the following problems:

1º When uploading the video is not stored Thumbnail:
[PS2] [KExternalErrors :: dieError] ERR: exception 'Exception' with
message 'exiting on Error 6 - Requested flavor was not found' in
/srv_apl/kaltura/app/infra/log/KalturaLog.php:83
[PS2] [KExternalErrors :: dieError] ERR: exception 'Exception' with
message 'exiting on Error 11 - thumbnail capture processing' in

[API] [kBatchManager :: createFlavorAsset] ERR: exception 'Exception'
with message 'Flavor [40] is none-Comply' in
/srv_apl/kaltura/app/infra/log/KalturaLog.php:83

2º When I try to capture a video image fails unable to store the image in the Remote Storage:
[API] [kFileSyncUtils :: getReadyFileSyncForKey] NOTICE: FileSync was not found
