Hi @eliasdiek

I believe this may have been resolved in version 5.8.1. Could you try updating to the latest version and see if this is still an issue?

Hi @lizkenyon
Thanks for letting me know about the version 5.8.1. I was thinking that the version 5.8.0 is the latest one as stated on the release page. Once I updated it to the version 5.8.1, the issues are gone.
