Problem with 1r1t mode Vivado 2021.1

[maxim1233]

I have downloaded new progect Vivado 2021.1. Up to this time I was working with the project Vivado 2019.1 in 1r1t mode. It worked correctly. Now I have saw some problem in this mode. DAC DMA not working correctly. When I set two_rx_two_tx_mode_enable =1 it' 2r2t mode the signal generation is good:

if I have changed set two_rx_two_tx_mode_enable =0 (1r1t), I have saw some distortion:

I have made ILA and saw output signal util_ad9361_dac_upack.

I have saw same picture in 1r1t and 2r2t modes

But in 1r1t mode DMA must pack in this position: I1Q1I1Q1, in 2r2t mode: I1Q1I2Q2.

Pls, help me..
