Cannot remove limits from graph

[#1]

I am using JMP 16 on Mac, and if the column has a spec limits (LSL / USL), then no matter what I am not able to remove them when making a graph. In the "Reference Lines" section there is a "Remove" button but it never works; I remove the line and it is removed in the preview to the left, but once I click Ok it comes back again. IS there a solution to this bug?

I am guessing that the column has a spec limit property turned on with a checkmark on the "Show as Graph Reference Lines". So when you remove the reference line from the axis properties, it does remove it, but then JMP sees the column property to add the graph reference line, so it adds it back. Clear the checkbox on the column property and the reference line should disappear.
