Workflow names ending with space characters stopped working

[mustafa1]

Last week I faced a problem,
Some workflows stopped working properly. They were working properly for around 1 year.
After a lot of tests, I recognized that the workflow names ended with Space characters more precisely they were ending with a double space character. ( I don’t remember why they ended with space characters, maybe a copy-paste mistake.)
Please kindly be informed that if you face similar problem space characters may be the reason.
