From what I recall , these issues were solved with patches pfSense package ages ago :

The bad news : you have to dig them up, here, in this forum or redmine.
The good news : 2.7.0 - coming out soon - will take care of things.

I was using 2.6.0 quiet long time, and issues (important to me) were solved after some forum interaction.

So, I found a GUI "bug". I had correctly set the prefix ID's in the "Tracked Interface" for each VLAN, but at the RA page, I mistakenly reinserted the prefix ID in the fields that are for static (full, not delegated) prefixes. Removed the static prefixes and everything now works. GUI should not let you enter static prefixes on a tracked interface, aside from fc00 or fd. And if it does, it should check if they are correct. One of the prefixes was ::1/64.

Manually forcing reinstall of pfSense-kernel-pfSense-2.6.0.pkg should get you onto the correct kernel after a reboot. But the kernel file you have already looks correct.
Once you do that can you ever be 100% confident of the install?
If reinstalling is very inconvenient then it's probably worth trying first but reinstalling and restoring a config is usually quick and easy.
