It's worth noting that I've found this error to be quite reliant on the GOCE tag, as it seems to overwrite the assessment ratings for the individual wikiprojects. There are some others that seem to also fit the bill, that just give wikiproject-esque templates without a rating.

Hi @MusikAnimal, thanks for taking a look at this - I did resolve this with removing (or hiding such as this edit [https://en.wikipedia.org/w/index.php?title=Talk%3AJimmy_White%27s_2%3A_Cueball&type=revision&diff=959452366&oldid=959450281]) the GOCE template on these items. I suggest there is an issue with this that template, and the lack of inate classing causes a conflict even if you add the parameter. Not sure if this needs further investigation of that template.
