背景：站点之前用FeedHub for Google Shopping进行feed传导，但是已删除FeedHub for Google Shopping里面传导的feed，目前只启用了Simprosys Google Shopping Feed插件。
问题：不理解为什么有一批不是用Simprosys Google Shopping Feed插件传导的feed自动同步到merchant center，目前只启用了Simprosys Google Shopping Feed插件，是与之前使用FeedHub for Google Shopping有关系吗？怎么排查shopify后台还有通过哪些方式传导商品feed？
Background: The site previously used FeedHub for Google Shopping for feed transmission, but the feed transmission in FeedHub for Google Shopping has been deleted, and currently only the Simprosys Google Shopping Feed plug-in is enabled.
Question: I don’t understand why a batch of feeds that are not transmitted by the Simprosys Google Shopping Feed plug-in are automatically synchronized to the merchant center. Currently, only the Simprosys Google Shopping Feed plug-in is enabled. Is it related to the previous use of FeedHub for Google Shopping? How to check the shopify background and what methods are used to transmit product feeds?
