I’ve just run the program for the very first time. Imported just one track from vinyl and started playing with click repair. So very true what you say about options for setting the different parameters - sensitivity, etc. I ran de-click on a 30 sec length of music and I was shocked to see just how many ‘clicks” the SW identified. I really must get to grips with what all the different sliders and options do before running de-click for real.For LP transfers I would normally run declick on the entire file. If elements has the same functions as RX then there will be various options regarding strength etc. Best to not over push otherwise you may get artefacts. If there are very bad clicks then it may be necessary to use other stuff that may not be available in elements. I do not have any experience with elements to know what you have. The advanced version of RX has additional functions for declick but I believe the basic declick is the same and should do the job for you.
What I find with the basic declicker in isolation is that it will clean up minor clicks very well so a run on the whole file works well. In some cases bad clicks will convert to a dull thump and these can be annoying to eliminate. The visual display of the information in iZotope is excellent so very easy to zoom in to see what is going on.
