# My drain design is no longer present in the ‘Apply’ wizard step.
**Symptoms**:
The Cut/fill map of drain surface in the Apply step is representing no cut and no fill.
The profile view in the Apply step of the drain is a solid red line.
**Causes**:
A drain design was created for one or more of the multiple drains in one project and the user went back to the Collect step and recorded another drain survey within the same project.
All drain designs were ‘overwritten’ when returning to Collect step to add more drains to the same project.
**Solutions**:
Design and Implement one drain at a time saving each as one project file.
Design and Implement each drain completely within one project before adding more drains.
Survey all drains, design them, and finally implement them without returning to add more drains.
