"Range rules must not overlap" error. Can't add additional rates by weight to shipping method even though rates have no overlap

Hello Forum folks,

I’m experiencing a new issue. I’m setting up shipping and when I try to save my additional rates for the same shipping method I’m getting the following error:


This is frustrating as you can see in the attached images my weight ranges are not overlapping. What is causing this??? I’m trying to ship before Christmas and this is really messing things up. Please help!

Hi Jordan! Did you manage to fix this issue? I am experiencing the same thing. I’ve been using shipping in the same way for a few years and never experienced this error before.
