Strange Properties appearing

I have seen it to appear in [0] and I suspect that this relates to this code {{#arraymap:{{{CentralIndexRef|}}}|,|y|[[CentralIndexRef::y]]}} in your Template:Article that creates an empty property.

I think if you remove the arraymap call then those arbitrary properties should no longer be created but this isn't really related to smw-core (this parser is provided by SF).

I think the x in CentralIndexRef in combination with arraymap causes this strange appearance, if you would use something else without x the issue might also disappear but again this relates to the use of arraymap and not smw-core.

I suspect that entries like CentralIndeB1Ref are empty (when created by the arraymap) and despite being void are still created as property reference hence the visibility in Special:Properties.

That makes sense, thanks MWJames. Replaced the variable x with y and rebuilt data and it's all gone.
