duplicated transaction display issue

[IBman1]

we have duplicated transaction display issue as showing in the following image. it could be caused by the logic behind the screen. it could be caused by the way the data is loaded. it looks like the screen is getting the data from several source. the explorer and the local data. strangely, this issue can disappear randomly. the logic behind this needs to be reviewed to find the what could cause the the load of doublicated data? is it due to multiple source? or is it due to doublicated donwload of the same transaction?
