RF60X fires too late with V6 II and Fuji X-T3 in HSS

Hi. I bought the RF60X. Triggering it from a Fujifilm X-T3 with V6 II, on shutter speeds shorter than 1/250 results with images where only a small bottom stripe is lit. To me it clearly means that the flash fires too late. I played with the settings a bit but I was unable to make it work. At the same time Canon 580EX II attached to another V6 II fires perfectly on time.
That's how it looks:

My transceivers are on FUJ.A.004 and the flash is on A.08 firmware version.
I would love to hear some suggestions how to solve my problem.
