[meta-ti] Trouble modifying defconfig for linux-ti-staging_rt recipe

I set my BBFILE_PRIORITY to "8" which is higher than meta-ti ("6") so
I would've thought it takes precedence over meta-ti recipes. My layer
is referenced in bblayers.conf and the layer's "conf/layer.conf" looks
like this:

=====================================================

# We have a conf and classes directory, append to BBPATH
BBPATH .= ":${LAYERDIR}"

# We have a recipes directory, add to BBFILES
BBFILES += "${LAYERDIR}/recipes*/*/*.bb
${LAYERDIR}/recipes*/*/*.bbappend ${LAYERDIR}/images/*.bb"

BBFILE_COLLECTIONS += "meta-acme"
BBFILE_PATTERN_meta-acme := "^${LAYERDIR}/"
BBFILE_PRIORITY_meta-acme = "8"

=======================================================

Pretty standard stuff. It's definitely finding my recipes so I don't
think that's an issue. What do you suspect might be going on?

Thanks,
