Problem with [loop offset=x]

Hi Eliot,
I have code like this

[loop type=post paged=8 offset=1]
[h3][field title-link][/h3]
[content words=40 sentence=true more=' Continue Reading → ']
[/loop]
[br][loopage]

First page is displayed correctly with one post skipped, pagination displayed at the bottom.
But if we click the number/pagination, the content is still the same, does not change to other page, but the number at pagination is changed.
If parameter “offset” is removed, it works.

Thanks
