X1C Nozzle Error Message

When I try to print anything on my X1C it shows an error message stating “Printing PLA material with nozzle may cause nozzle damage. Please fix the error above otherwise the printing can’t continue”

I’m not sure how to fix this, as the as my 0.4 nozzle has never prompted this, as well as it isn’t clogged or any thing like that.

How do I fix this?
