Carbon damage?

Hi all, new on here and hoping for some advice..

I have a cannondale supersix frame, on my last ride out i heard a ping and on closer inspection when i got home found that the metal chainstay protector had fallen off taking the paint and a small amount of carbon with it. (Pic attached).

This is the first carbon frame i’ve owned and not sure if i should be concerned.. it doesn’t feel weakened and there is no sign of a crack.. there was no impact, so is there anything to worry about or can i just stick a new protector on and get back to enjoying the summer?

thanks in advance..
