This week, we have a number of reports, in Blogger Help Forum: Get Help with an Issue, from blog owners who like to monitor the Google+ +1 counts, for their posts, using the dashboard Posts list.
The ability to observe, at a glance, the +1 count for any given group of posts is useful - and popular with some folks. I use it, myself, with newer posts in this blog.
Unfortunately, my Posts list shows no +1 counts for recent posts, for some Posts lists.
It appears that pagination of the Posts list affects ability for any Posts list to have the +1 counts displayed.
In some cases, +1 counts will not display, for a paginated Posts list, on the first display page of the list. Subsequent display pages, seen by hitting the ">" button at the top, will show +1 counts for the posts.
In other cases, +1 counts will display, for a paginated Posts list, on the first display page of the list. Subsequent display pages, seen by hitting the ">" button at the top, will not show +1 counts for the posts.
Posts lists which are not paginated (have only one display page) do not seem to be affected by the problem.
Blogs with smaller "All posts" lists, and blogs with smaller Posts Label lists, may not show the problem - so not all blog owners will observe the problem. Also, owners of blogs which receive few +1s - and who do not use Google+ for posts distribution - will probably not observe the problem, either.
You may be able to examine this effect on your blog, by choosing Labels which have more, or less, than the number of posts compared to the Posts display page size (100, 50, 25, or 10) - and by changing the Posts display page size, to a different number.
We have a rollup discussion, in Blogger Help Forum: Get Help with an Issue, where we are attempting to diagnose the spread of the problem. If you find your blog affected by this oddity, and are able to answer a few questions, your input could be useful.
As always, I will respectfully request that you keep your replies, in the rollup topic, brief and relevant. And please read the first post in the topic, for instructions how you may participate in the diagnosis of the problem.
(Update 2015/03/09): This problem appears to be resolved.
