Two identical strings reported as different

TestProject Addons, SDK and Coded Tests
#1

I am using String Util add-on for comparing two strings in my project.
One string is predefined and saved as parameter and the other is extracted from PDF file in runtime.
For some reason TestProject always returns an error when running tests and says that strings are not identical and the comparison result is -19
I tried putting both strings (which are acquired from the Report) in Text diff comparator and it turns out that both strings are in fact identical. testproject

You can see all the test results in the above screengrab.
