Hello Tikaram,
Thanks for passing it on to the development team. Since the plugin works correctly for me with my modification, I uploaded the original version to the development website.

The modified version is now available on my live web space

The changes are also described there.
Maybe there is a solution in the next version
Greetings and thanks again
Dieter
