Faulty TCAS behavior

[ekosif]

Hello!

I got very weird TCAS advisory during cruise. As can be seen from the screenshot below, I got TCAS alert even though there is 6500 feet between me and other aircraft, and there is no possible conflict as both aircraft were heading almost opposite sides. And this was not the only one I got, I almost got TCAS alert every traffic flew under me, some of them were not even visible in the MFD due to huge altitude difference.

Also those green/red bars in the PFD was there for entire flight even after clear of conflict callout.
