Don't worry about it.
I didn't create the profiles, so I would be the wrong person to ask to be honest. However, I looked through the hundreds of pages of existing posts and it does appear that this TP was chosen for efficiency. Essentially what the Act 1 profile does is visit all known spots where the Keywarden could be located, starting at the very bottom. Running from the Cemetery puts you right at the bottom of the map. Teleporting directly to the Fields of Misery waypoint however, puts you more or less in the middle, causing quite a bit of backtracking that can be avoided by running in from the Cemetary. While it would be possible to rearrange all the POIs the bot visits, I am not sure whether that is worth my time, considering that it will likely result in a longer run overall and that the problem with running in from the Cemetary is a DemonBuddy bug of the current stable version that has already been fixed in Beta and that will eventually become the stable version soon. Personally I run DemonBuddy Beta anyways, so I never actually experienced it. I suggest to give the current DemonBuddy Beta version a try. If it doesn't fix that issue either, I will gladly give it another look.
I have added a feature to the new version of the plugin that allows you to toggle combat off until the Keywarden is found. It is currently in testing and will likely be released later today or tomorrow.
Thank you for your kind words. You are very welcome

I suggest switching to DemonBuddy Beta until the navigation fixes have made their way into the stable version.
