Hey there, sorry for the delay, had a huge ice storm knock out power for 2 days. 
It is hard to tell from the images what is causing that look, if you could zip up a copy of the project and upload it to DropBox or other similar site and then PM me the link I will certainly take a look for you! Or if you could PM me some more images showing the Gerstner formula & Cluster I can try and figure it out for you. It’s most likely an with the Gerstner formula itself, or the values you have set for the WaveLength/Amplitude/Steepness values in the Gerstner Cluster.
