Flattened surface not displaying deformation plot

Im working with some customer files that have fairly complex geometry. I need to flatten the surface and see the deformation plot to know where to put splits, darts, etc. The problem is that the deformation plot is now showing. Below is an image of the flattened surface. I activated the deformation plot (which usually works fine) but the plot is not showing. When I hover over the surface it gives me the local value so it did the process but the plots not showing. I'm not sure what to do. Any help is very appreciated!!!
