Incorrect data in MyLog Grid

[GreekSpy2001]

Hi

I posted this on the 2nd of feb

"USN E6 164409 HEX AE041B caught just now.  See screen shot"

into the interesting military aircraft thread.  Along with a screenshot. 

However, now when I look into the Mylog Grids it shows only a hit from today (6th Feb) and not the hit from the
2nd? 

I have not done anything to mylog, there are plenty of hits of other aircraft for the 2nd.  Is the data being over written?
