We have encountered a significant issue with MetaBox where taxonomy select fields are not saving data correctly under certain conditions. Specifically, when we use two or more select fields associated with the same taxonomy within the same meta box, the data from these fields appears to be shared or overwritten, rather than saved independently for each field.
The purpose of this field is to replace the default WordPress meta box for taxonomy and offer more options to control how it displays.
For this reason, if you have two taxonomy fields, and select different values for them, after saving, they still show the same value.
Regarding the issue with taxonomy select fields not saving data correctly when multiple fields are associated with the same taxonomy within the same meta box, we understand this is noted in the documentation.
Could you please let us know if there is any workaround for this issue? Perhaps a custom hook that handles this during the save_post action?
