not working properly with some multisite domain/subdir maps

Hi there,
I just wanted to say that the nginx map generation isn’t working properly when a separate domain + subdir is mapped to a subsite on multisite using the new (as of wp 4.5 I think) site URL setting.
For example, I have a site, let’s call it example.com. On that site is example.org as a subsite, domain mapped using the URL setting of the subsite. I then have a totally unrelated site, example.org/subdir, which is yet a third subsite. However, nginx helper makes an entry for example.org, example.com, and example.com[/subsite/] (where [/subsite/] is the one I now mapped to example.org/subdir). I *think* this might be because it isn’t properly (at all?) supporting the new way of mapping URLs to subsites in wp core, but instead is using old settings from the WPMUDev domain mapping plugin, which I just deactivated, and my site now at example.org/subdir which was originally at example.com/subdir2 is showing as /subdir2/ in the map.
Anyway, just wanted to let you know that either it isn’t supporting the wp core version of domain/URL mapping, or maybe it isn’t at all.
