I do but it must have been an intermittent bug. 3x I tried to overwrite that initial file. The new file was saved (which overwrote the test2 file), but the new colors were not being added. However, today everything seems to be working fine although I had 002 all along. So disregard this report and if it pops up again, I’ll notify you. Thanks.
