I've installed your Multiple Store View Pricing for Magento 2 extension, then set up price to store view in catalog but when editing the price for different store views, it switches back to global.
In this case, could you please try to set the price scope to “Store View” again and save? After that, please note to flush the cache.
For more information about product, please refer Multiple Store View Pricing for Magento 2 page.
If you need any further assistance, please feel free to contact us.
