Signs lit with glow ink before 1.17.10 update are no longer lit after update

Signs that I had lit with glow ink prior to 1.17.10 update are no longer lit following update to 1.17.10. I have found this in both my solo creative world and my friend's survival server. (For clarity the text is still dyed the same colour I died it, just no longer in lit state.) I have had to use additional glow ink to relight them all.
