These notes usually indicate one or more linear dependencies in the design. That is, a linear combination of one or more factors can exactly duplicate another factor's values.
Singularity Details are shown at the top of the results window. Examining these details should assist in determining which factors are involved in the linear dependencies. You can then adjust the model by removing factors to eliminate the dependencies. It is suggested that you remove one factor at a time to determine if the issue is corrected.
