This theme is not set up in a way that Loco Translate can understand. It uses the text domain “swiftframework” but does not declare it. It doesn’t provide a properly named POT file either, so Loco picks up the wrong template from another text domain used by the same theme.
There are no fixes for these problems, unless you are the theme author.
To have your translations loaded, you will have to manually rename the MO file you’ve saved, from “neighbourhood-lt-LT.mo” to “swiftframework-lt_LT.mo”. You’ll have to do this every time you save it.
Alternatively (if you’re a coder) you could manipulate the MO file path using the load_textdomain_mofile filter.
The next major version of Loco Translate (2.0) will be compatible with this theme. Until then you should consider it incompatible.
