Curve domain in properties panel mismatch


I used Reparameterize on a curve because it was misbehaving in a script, and while according to IT the domain was changed to 0 to its length, the Details in the properties panel still say what it was before, an interval of negative numbers, which I don’t think my script is set to manage completely correctly. But the script does work right now so it must have changed. Where are the different numbers coming from?


Jim can you send me that curve? I just tried Reparameterize > Automatic and What (as well as Domain) agree with the expected (zero to length) numbers…
