Exclude current function doesn’t work correctly

Hi Tom,
I have GP Premium and am using WP Show Posts on my website.
There’s one function of this plugin that unfortunately doesn’t work properly.
There was already a support ticket regarding this:
https://ww.wp.xz.cn/support/topic/exclude-current-doesnt-work-if-using-post-ids/
But it doesn’t seem to have been fixed.
Here’s how I would like to use it:
I have three pages with IDs 1, 2 and 3. At the bottom of each page, I would like to have a WP Show Posts list linking to the other two pages.
This is why I created a list showing only IDs 1, 2 and 3, with “Exclude current” checked. But for some reason all three pages appear…
Thanks in advance for your help!
