Revision of import on Bitrix

Hello.

Site on Bitrix Business, uses the solution AsproMax - start.max-demo.ru/

Problem.

1. When importing CSV through the standard module and through the Excel import module, elements are created, but only text and numeric values are assigned. References and lists are not affixed. For example, if you make the field type "text" and register any text with text, it will recognize and prescribe.
And if you create a directory and select the id of the directory item or the name of the directory item, you wont read it.

2. When manually creating items through the system, it is not possible to set values for all fields of the Reference type. For some reason, it is reset when you try to select an option for the second field. Multiple selection also does not work, provided that the infobox settings indicate that the value is multiple.

Thats what needs to be solved :)
