Yes, there are severe inconsistencies and not only in citation counts.
Also some bibliographic data (co-authors) have been erased!

There is a "Maintenance Alert" from provider:

We are currently experiencing performance issues with Web of Knowledge 
access, search and navigation. Our technical staff is working to resolve 
the problem as quickly as possible. We apologize for any inconvenience 
and appreciate your patience.

Thus, i recommend continued usage of the previous version still 
available (until end of the year) at the right-hand side under
"Support, Tools, Tips":

[Access the previous version of Web of Knowledge]
