Why I have so many veth interfaces in firewalld Zone

I have a server that runs docker and firewalld, everything works fine but I **cannot** reload firewalld with the command

firewall-cmd --reload

One thing that I notice is in the result of this command

[root@localhost ~]# firewall-cmd --zone=public --list-all
public (active)
  target: default
  icmp-block-inversion: no
  interfaces: eth0 veth0008eb7 veth00197d0 veth0023d4b ...(10K of these)... veth036eaae

I have over 10K of veth..... interfaces, that's insane. - I try to run a script to delete all of these interfaces but was not able to reload. - Each time I reload firewall-cmd --reload, the server is unable to connect How do I fix this? Thanks in advance.
