Hi Potekhin Vitalijj,
I am really sorry for the delay of this reply as it is a weekend for us here.
You can apply this following css code in your template css file, so it will hide it.
div#discuss-wrapper .discuss-item.is-featured .discuss-statistic.pull-right,
div#discuss-wrapper .discuss-item.is-resolved .discuss-statistic.pull-right {
display: none !important;
}
div#discuss-wrapper .discuss-statistic {
display: none !important;
}
Hope this help.
