Orderby “Update Date” not working

The parameter update_date not working in Shortcodes and WPDM Gutenberg Block plugin. Both not working.
There must be a conflict inside codes.

For example: check wdpm-function.php line:706 below please

    $orderby = in_array(wpdm_query_var('orderby'), array('title', 'publish_date', 'updates', 'download_count', 'view_count')) ? wpdm_query_var('orderby') : $orderby;

Order parameters are:

title
publish_date
updates (what is it?)
download_count
view_count

There is no “updates” parameter in your shortcodes.
Even if I changed it from “updates” to “update_date” in wpdm-function.php did not fix the bug.

Can you please fix it?
Sorting items in Update date is a major need. It requires to fix.

Thank you.
