This is a known issue with First Person template that’s been fixed for 4.10 (UE-20152). If you’d like to continue working in 4.9, this shouldn’t cause any additional problems that we’re aware of.
reported bug was only for First Person template. It looks like you’re seeing a different error, so I’d like you to create a new post in Bug Reports section with as many details as you can provide, including which template you’re using. I’ll make sure someone on support staff gets assigned to look into it. Thanks!
