Need some assistance with Atlas please

I got the texture to process but now when I process the .raw to .chu I have 2 points that cause an error. The file size is 2049x2049. One point exceeds max and one point exceeds min. I have tried setting the error metric from 10 to 0.5 and still have the same error. I also tried a different .raw file (1025x1025) and the same 2 errors show. I am using 3LDT for creation of the raw file. I thought it may be the program so I started Terragen and made a new terrain (513). Same issue (one point excceds min and one exceeds max)

I am using the script wrote by Neo Binedell (nothing to do with the error) and the settings are:

SIZE: 2048
Square Size: 1 - 8 ( tried all settings from 1 to 8)
Height scale: 0.00390625 (1/256)
Error Metric 10.0 to .5 (tested in .5 steps)
Tree depth 1 to 8 (Tried all settings)

Tried several combinations but can't get rid of the 2 error points.

I am lost on what to try next.
