JForex Dukascopy Bank ver. 2.27.2 DEMO
JForex API ver. 2.9.3

This one is strange. One second updates appear to be happening
to the "Duration" column when there is a Remote Run indicating
the amount of time the Remote Strategy has been running.

I was going to do a video of it, but thought that was a bit too much.
In the two attached shots, note that the Strategy which is circled
is showing 2 different duration values.

These 2 values were each on for enough time for me to use the
Snipping Tool to get the two shots. They alternate on a 1
second update cycle. The correct value appears to be displayed
for the longest time. The incorrect value is on only momentarily.

We get value A, then B. And then it repeats every second.

You must have some synchronization issues with the JTable
update, I'd suggest, in order to get this kind of benign
corruption of the display. Check that SwingUtilities are used
to update the table, and that any needed synchronization
is there, but you know that

Not urgent,
