Number of associated signatures for a signature-set appears zero in REST API and GUI. /mgmt/tm/asm/signature-sets/{UUID} returns 'signatureCount' of which value is incorrectly shown zero. Signature set screen in the GUI shows list of signature-sets with number of signatures of each sets. This number is incorrectly displayed zero. Security ›› Options : Application Security : Attack Signatures This is a cosmetic issue. Signature enforcement is performed for the affected signature-set even though the number is reported as zero. By selecting an affected signature-set in the GUI, you can see the associated signatures.
