layout messed up for Prince_Productattach module for magento 2.3.3

I am using a Prince_Productattach module on my Magento 2.3.3 CE, how can I troubleshoot some issues on the frontend.

  1. as the diagram shown, the product attach block display on two places, i didn’t customize it, how should i find out the reason for this duplicated?

  2. The Tab for Download (attachment) on the product detail is the first at the moment, I think normal this tab better put behind, the first should be the product basic information, how can I change the order of the tab on the module?

Here’s the layout catalog_product_view.xml, will you find anything I should adjust to do what mentioned above.
