The /interface wireless manual-tx-power-table menu does not show the current (effective) tx power. This menu is where you can manually set tx power for each rate separately; these settings are only effective when tx-power-mode is set to manual-table. Please consult this manual page for more details.

Viewing current TX power is not currently supported for AC boards. This is a known issue.

Thank you for replay. I understand now.

If I will use tx-power-mode=all-rates-fixed rates-fixed are respected?

Yep.
