ID:140093 Can't specify security level "<name>" for region "<name>", because at least one signal of the region has a higher security level

CAUSE: You tried to set the security level of a secured region to a value that is lower than the security level of at least one of its signals. A region must be as secure as its signals.

ACTION: Review the security requirements of the design. Consider lowering the security level of the signals, and then retry the operation.
