See this issue on the RAD repo, please check the concerned config file (RAD_Surface.cfg) for more details about how it is configured.
The first obvious issue is that the list of ScienceSubjects used in the core CollectScience generally has duplicates, even though nothing suggests this is due in any way to the configuration file.
The second issue is that those subjects are never truly counted as having their science recovered : it shows as much when you transmit the experiments during flight (showing green checkmarks next to the subject title and hiding the recovery method), but after the vessel is recovered, the list becomes totally unchecked once again. The core CollectScience parameter is never counted as complete.
On certain times, after recovering the science (not transmitting), the list becomes checked at the KSC, but the CollectScience parameter still doesn't get complete.
After checking the source code in this repo, it seems that a hook called OnScienceRecovered should be fired, with verbose logging, but no such lines appear in my log. Apparently ALT+F10 shows a debug screen where this verbouse output is probably located, I will investigate.
My mod list is pretty extensive, which may indicate that some undocumented incompatibilities are the cause of this issue, although a couple of other users have reported a similar bug in RAD's KSP forum thread.
