Make compatible does not work

For example:

C:\Users\User>fac install UPS-up -i
Installing: UPS-up 0.2.2...
Downloading: UPS-up_0.2.2.zip... 100 %

C:\Users\User>fac make-compatible UPS-up
Unpacking: C:\Users\User\AppData\Roaming\Factorio\mods\UPS-up_0.2.2.zip
Removing file: C:\Users\User\AppData\Roaming\Factorio\mods\UPS-up_0.2.2.zip
Game version changed to 0.16 for UPS-up 0.2.2.

and the contents of C:\Users\User\AppData\Roaming\Factorio\mods\UPS-up_0.2.2\info.json:

{
    "name": "UPS-up",
    "version": "0.2.2",
    "factorio_version":

It's strange that it doesn't even have the closing bracket, and this is happening with all my incompatible mods.
