GPrename unable to accept multiple file parameters

[Alistair]

Behaviour is accurately reported elsewhere:
https://forums.linuxmint.com/viewtopic.php?t=222665

I find exactly the same; multiselect files from nemo/bulk rename and a random file from anywhere is displayed. Also, if in nemo, action is described as gprename only, gui is instantiated, then self closes. action must be as gprename %1 or gprename %F (parameter needed).
With any parameter the behaviour is the same; no files selected are shown.

I have uninstalled and reinstalled to no avail.

I have uninstalled and replaced with krename which works perfectly with nemo with no parameters necessary.
Thanks, Alistair.
