Contour Labels show the wrong elevation. #44

I set up UTM 15 in US feet and contoured an area shown on link above. Contours look good. However, the labels show the wrong elevations (grossly wrong). I change to map units, and the numbers are still wrong. Used the profile plugin to verify contours are correct, but labels are wrong. This is a major problem.

@moody1951 That sounds very odd.. I can't really comment further without more information - it works for me with a different data set. If you provide a sample data set that demonstrates the issue (just the points you are contouring), the contour settings you are using, and the QGIS version information (eg from Help | About) then I could see if I can see anything obvious. Otherwise I can't offer much.

It might be worth checking that the labels match the contours you think they do (ie are not offset a long way from the contour). Easiest way is to use the info tool to read the label attribute of the contour..

Chris,I figured it out.  It was my mistake.  I was labeling IDs instead of elevations. I am transitioning from another GIS package and made a mistake.  Thank you for checking. On Thursday, September 24, 2020, 03:43:52 PM CDT, Chris Crook notifications@github.com wrote:
