Malformed Paket in tcpdump

Dears Good Morning,

I have an issue that Backend server i can connect directly but cannot connect through F5 VS .....

VS configured to listen in 443 and have Client SSL Profile and http profile ( note that issue remain even if i remove the SSL profile to simulate connection as directly to backend server )

when i tried to see tcpdump i found the following

what is malformed packet mean and this is capture for direct connection to backend server
