Confirmed. The subentries aren’t shown if:

  - entries that share a subentry (level 2) are indexed
    consecutively, and

  - these entries are different but belong in the same register
    section (same initial letter)

Example:

    \starttext
      \placeindex

      \page

      \index{a+foo}        whatever %% shows up
      \index{aa+foo}       whatever %% doesn’t
      \index{aaa+foo}      whatever %% doesn’t
      \index{aaaa+bar}     whatever %% shows up
      \index{aaaaa+foo}    whatever %% shows up
      \index{aaaaaa+foo}   whatever %% doesn’t

    \stoptext

If you s/bar/foo/ in the fourth invocation of \index, only the
first entry (“a”) of the register will have the subentry “foo”.
Change the initial letters of each entry and all subentries are
printed.
