Thanks for the report, and sorry for the slow reply.

I see the same thing on my end as well, using your example and the
example from the message you linked to:

--8<---------------cut here---------------start------------->8---
#+COLUMNS: %40ITEM(Task) %12Effort(Estimate){est+}

* Estimate
** Little Thing
   :PROPERTIES:
   :Effort:   1.0-5.5
   :END:
** Big Mess
   :PROPERTIES:
   :Effort:   8.0-30.0
   :END:
--8<---------------cut here---------------end--------------->8---

It looks like the fix from the above commit (c1558d34d) was later broken
by the transition to the org-duration library in Org 9.1, specifically
7e8cf5f4c (Use Org duration library, 2017-02-08).
