BFM and SBFM are high security features intended to quickly help customers under active attack stop as many bots as possible. Due to the high security threshold, false positives do sometimes happen.

BFM has limited control. You cannot bypass or skip BFM using the Skip action in WAF custom rules or using Page Rules. BFM will be disabled if there are any IP Access rules present.
