Image titles have dashes upon upload

I’ve noticed a weird issue that came up randomly on my site. I’ve noticed in the last couple days that when I upload images they no longer get a proper title. For example, I will upload an image called Funny Dog.jpg the title WordPress would usually give it is Funny Dog. However when I upload it now it generates the title as funny-dog. I’ve deactivated all my plugins, but this hasn’t made a difference. Has anyone else experienced this issue?
