Link fields Missing

All,

I updated Link to 7.x-1.6 the other day and it seems to have wiped out the link fields. I updated Context at the same time, but can't think of any reason that would affect Link. I updated both on a test server with a duplicate site this morning and that site is fine.

I've tried to uninstall 1.6 and re-install 1.5, but it didn't revive the fields. I've tried to change it from required, to optional, etc. and none of those settings make it appear. The fields don't even appear in the edit view of the link in the content type (see pic labelled "link").

The only way I can get it to show up in the content type form is to change the number of entries allowed from 1 to anything higher and it has them show up as if they were menu items (see second picture labelled "case").

Any ideas?

Thanks!
