Discrepancy in the total of positions displayed

I feed to you from two sites.
Site 68135 – EGNC – Gerry55 Site (1)
Site 68139 – EGNC – Gerry55 Site (2)
Site (2) is OK

But site (1) has a discrepancy in the total of positions displayed in the Nearby Sites column 215,074 but showed on the 23-04-18 309,431 in the Positions Reported column.

Checking on other sites they display very similar totals in each column.

Can you please tell me what is wrong with my setup?
Gerry
