How to set up uploading to YandexMarket on Umi.cms?

Question

XSL & XSLT

Hello.
When uploading goods to the Yandex market, the module checks the color and availability (if there is a choice of color),
but if there is no choice by color, then the module does not check the availability of the goods and unloads it anyway.
It is necessary that in any case it is checked whether there is available
Help!
