Help! VLAN rule isn't always applying...

In an effort to learn networking, I'm migrating my home network to take advantage of VLANs. I've set up OpnSense and hooked everything up and I'm trying to get the rules situated but they're not making sense to me now.

I've got a "management" VLAN10 a "client" VLAN20 and a "wifi" VLAN30.

VLAN10 has a hassio host (for home assistant) [172.27.10.5]
VLAN20 has skeeter my desktop computer [172.27.20.4]
VLAN30 has pixel my phone [172.27.30.40]

I wrote a very simple rule in the VLAN20 ruleset to allow skeeter to connect to hassio, works great! But for the life of me, I cannot figure out why I can't write the same rule for pixel and have it work on VLAN30.

I've attached the live log that I captured showing both blocking and passing packets that look identical! Also my rule set for VLAN30 and VLAN20. I have skeeter listed as one of the "management_hosts" so it matches that top rule immediately when I connect skeeter to hassio. I created the top two rules on VLAN30 to try to allow pixel to connect but it's still being blocked. :(

Please help me solve this, I really want to understand where I'm missing understanding on this...
