Are the values in the L5K? I guess they would be, I don't have software to check right now. If the values are there then asking Travis for this feature is possible.
As for the bugs, I had some bugs when I first tried. I emailed Travis and he had a fix that day. You aren't going to get a fix on this site. I recommend posting on IA site, there is a post you can use, https://forum.inductiveautomation.com/t/l5k-parser-issues/48613
If you have access to Emulate, I would use that instead of simulation tags. If you are an integrator and have a toolkit, then you have it.
