Problem: I am unable to set a long excerpt length in a Single Field block. The length seems to be limited to the number of words or characters in the excerpt.
Solution: Our developers are aware of this limitation and are working on a solution in a future release. For now, a workaround is required. Temporarily edit the previewed post and give it a very long excerpt, then you can edit the Single Field block's word count limit to use a longer excerpt length. Revert the post's excerpt after setting the length correctly, and the longer excerpt length setting will persist until you edit the View again.
Problem:
Checkboxes field filter is not working as expected.
Solution:
It seems that at some point the setting to save 0 for non selected option was activated. Check this screenshot http://prntscr.com/11c2nac
Toolset stores the values of a checkboxes field inside a serialized array and perform the search using the "LIKE" operator. When an option is saved with 0, it matches the LIKE operator. This gives unexpected results.
The setting is configured to save nothing when an option is not selected. You will have to manually update the erroneous posts on a search to save the correct values on the database.
