Multicast packet could not pass into the inside network

We have two ASA 5512 firewalls and there is a master backup redundancy between each other.  Also, I configured FW-2 as primary and FW-1 as secondary. When I power on devices at the same time, sometimes FW-1 become master or sometimes FW-2 become master after power on. When FW-2 become master, the multicast packet could not pass into the inside (YKI) network. I get the Wireshark outputs from inside (YKI) and outside (YSHA) way when the problem occurred. You can find in attachment. Also, you can find topology.
Also, I solved this situation in this way. Firstly power off the FW-2. After that FW-1 become master and multicast packets pass into the inside. After that, I power on FW-2 and power off FW-1 and FW-2 become master. I checked the situation but I observed there is no multicast problem. Power off FW-2 and power on again solved this situation but I did not understand what is the problem?
