connectivity kit copy paste anomoly

[Liamtoh Resu]

Extra characters are appended to the source code is copy and pasted from the windows clipboard to a new program created with the hp connectivity kit.

An attempt to run the programs produces an error.

An extra line is revealed when editing the program on the calculator
when using the check feature is used.

Deleting the extra line allows the program to run correctly.

Question: Does the above process reflect "operator error" or is it
a bug/feature of the hp prime/connectivity kit/windows ecosystem?

Thanks in advance for any feedback.
