if i put in 2, it should only list out 2 page maximum, right? ,but it will keep load the first page repeatedly, again and again forever. if i remove the setting here, it will load properly.
The Taxonomy Terms block automatically provides a Taxonomy Terms source for dynamic content blocks.
The Taxonomy Query source that you show here is only available when used in conjunction inside a Query block that is set to a Terms query.
The reason “current” does not apply to the Taxonomy Terms block is because you are in the Site Editor, that doesn’t apply to a specific post. I suggest you use the Dynamic Preview function to be able to use the “current” source.
