This is the system standard behavior. Custom entries on the configuration activity 'Define Number Ranges For Sales Documents' (ID: 102819) can be changed, however they can be locked on specific scenarios to prevent inconsistencies.

Except in very rare cases, changing an existing interval should be avoided. Revising an interval is a critical change that could cause considerable correction efforts. 

The intervals cannot be changed when they fit in one of the scenarios bellow:

• It's a pre-delivered number range intervals.
• The lower limit of the interval has been used.
• To alter the upper limit of the interval will create an overlap with other intervals.

Note: it should be avoided to change the number range status except in rare cases. 

• Changing the number range status to a number that is smaller than the current number range status is likely to prevent the system from creating new documents in the future (for example, duplicate record errors).
• Changing the number range status to a number that is larger than the current number range status can cause gaps in document numbering. This can lead to significant issues in the future if subsequent numbering is required.
