Invisible Text

I ran a spell check on my drawing and a bunch of text is being caught, but the text is invisible. (See screenshot) I have all the levels turned on, and I even turned on all the view attributes. I cannot select or delete these text entities. If I export the DGN to a DWG and open it in AutoCAD, I can see all the text. Has anyone come across this and how can I fix/delete the entities?

Thanks,

Chris
