Geodata for Terms Assigned to Feeds Disappear when Feed Items are Imported

The ability to have an MN Feed's tag(s) automatically applied to all news stories imported via that Feed is a *huge* benefit of 6.x.1.1 -- it saves us a horrific work-around of using Yahoo Pipes and a whole slew of regex to get needed feed-specific tag into every individual feed item! But I'm having a very strange problem where tags' geodata disappears once items are imported.

Here's whats happens:

1. Clean install of Managing News 6.x.1.1

2. Go to /import/terms/delete-items?display=views-mode-map and delete all the default terms.

3. Go to /import/terms?display=views-mode-map and import CSV of our desired terms, including their lat/lon data.

4. Go to /admin/content/taxonomy/1, and verify that terms imported with lat/lon data. They do, and the "Use for term extraction" checkbox is checked.

5. Go to /node/add/feed, and create a new feed -- taggging it using on of the just-imported "tag" terms.

6. Upon creation, feed items are imported, and the map in the right sidebar shows no dots.

7. Go back to /admin/content/taxonomy/1, and check out the term in question. It now has no lat/lon data, and the "Use for term extraction" box is no longer checked.

This happens every time. I can go back to /import/terms, and re-import my CSV file (after overriding that feed importer at /admin/build/feeds/edit/terms/settings/ExtractorTermProcessor to "Update Existing Terms" -- at which point the geodate and "Use for term extraction" setting go back to the way they were in Step 4. But the next time a feed updates, the same purge happens.

I have not yet tested to see if this will happen for MN's default location terms if they're assigned to a feed. But is there something I'm doing wrong here, or is this a truly a bug with the new term-inheritance feature?
