Problem Adding a New Scope

iTelescope's T18 is not currently in VPHOT. I tried to add an entry for it but it is not working. For the TELESCOP keyword I used 'ACP->iTelescope.Net T18'. Plate solving is not working (i.e. WCS is red), so I assume my entry is not being matched to the image. When I look at the other iTelescope VPOT entries they use GRAS0xx for keyword, but when I look at the FIT headers of those images they say something similar to 'ACP->.....

Is there something unique about how iTelescope headers are processed? Or am I making a mistake in my entry somehow?
