Elements 23, suddenly not showing DeNoise, Sharpen or Photo AI!!

For reasons beyond me, when I go to Filter in the Editor, it suddenly wasn't showing Photo AI but initially was still showing Sharpen and Denoise. Now, I saw there was an update today so thought maybe that was the culprit. I have now updated Photo AI but when I go to Filter in Editor, it is not showing any of the plugins!! No Photo AI, no DeNoise and no Sharpen!! Any ideas on how to fix this? I count on using all three of them within Elements 23.
