CIC compilerr IP with alken

Hello.

I work on signal processing.
I try to use CIC compiler 4.0 (rev. 10) with aclken input in Vivavo 2016.1.
When I run my simulation with alken holded in '1', everything works and looks good.
But when I try a simulation with aclken active only every fourth rissing edge of aclk, CIC compiler output never generate m_axis_data_tvalid signal.
It is no problem in simulation short time.

Any ideas what I am doing bad?

Difference of CIC input signals and respond for identical CIC is shown in picture.
