Trade site not showing 1400 pdps two handed Vaal Axe (Filter issue)

The trade web site shows my axe as 1402.56 dps (same as POB), and yet when I filter 1400 axes it doesnt show.

Only when I filter 1399 dps it shows, which means its being skipped by any person trying to find 1400+ high dps axes.

This is not the first time I encountered this issue with a two handed Vaal Axe,
I dont know if it happens for all axes or all weapons in general.

Thank you so much for the prompt reply and call to action!

I just got another exmaple:

1201.2 Vaal Axe - doesnt show on search results when filtering 1200 pdps.
