watch file is present but does not work?

When I upload my package contextfree to mentors.debian.net, in the QA information I get this:

A watch file is present but doesn't work

-- Scanning for watchfiles in .

-- Found watchfile in ./debian

-- Scan finished

My watch file looks like this:

version=4

options="pgpsigurlmangle=s%$%.asc%,dversionmangle=s/\+dfsg[0-9]*//,repacksuffix=+dfsg1" \

https://www.contextfreeart.org/downloads.html \

download/ContextFreeSource([\d\.]+)\.tar\.xz debian

When I run uscan on my system it works just fine. When I bumped the upstream version, uscan determined that local was stale, downloaded the new source version, downloaded and verified the gpg signature, and repackaged a new orig.tar.xz file. Subsequent runs of uscan determine that local was up-to-date but downloaded and verifies the gpg signature anyway.

What check does mentors do that my watch file is failing?
