Error with woo notification pasting extra string of code

Hi there,

I am having an issue with added code being added to the string of the sentence: pur/admin.php?page=woocommerce-notification#messageschased a

Please advise why this is occurring it only occurs on messages where it says:

‘XYZ purchased a’ if it is in regards to how many people are viewing the product it is fine. I bought the product via Code Canyon on 20/06.

Thanks
