Dear [name removed]?

Could you help me please.

It seems that the number of dredging zones is limited by 99. How can I increase the limitation?

Thank you.

Hello,

did you try that it is only 99? The number of dredging zones should be between 1 and 899.

For clarification: The identification number for the dredging zones should be between 100 and 999.
