The "Drupal\Core\Validation\Plugin\Validation\Constraint\RangeConstraint" constraint can not use "minMessage" and "maxMessage" when the "min" and "max" options are both set. Use "notInRangeMessage" instead.

Should have been fixed in 🐛 Cannot set both min and max values for numeric fields Active .
Perhaps it customisations that are interferring. Will double check later this week.

This should already be fixed in previous release but dev branch also has some additional logic that should make it more sound as well. Can confirm if this is still an issue in dev at least.

I'm not able to reproduce this on latest release. Feel free to reopen with steps to reproduce if you're still seeing this issue.
