Deleting a tag from a bound branch

[Eli Zaretskii]

In a bound branch, I typed the following command:

  bzr tag --delete EMACS_PRETEST_23_0_96

which connected to the upstream repo and then said

  Deleted tag EMACS_PRETEST_23_0_96

So far so good, but after a "bzr update" on a different machine,
"bzr tags" still shows the same tag.  What is wrong?

I deleted that tag because its related revision does not exist in the
repository ("bzr tags" shows "?" in place of the revision).

In case it matters, the version of Bazaar used to delete the tag is
2.4.2, the version on the other machine is 2.1.4.

TIA
