ios 10.3.2 Can't Delete Safari Website Data

Just updated to iOS 10.3.2 on my iPhone 6S and still can not fully clear out website data. Right after the update installed the website data cache was cleared. However as an experiment I went to weather.com and sure enough there was an entry by them in my website data. After numerous attempted to delete this it refuses to clear. This has been an ongoing problem (happens on many websites and there are many complaints) which I was hoping would be addressed in this update, but I guess not. At this point the security of Safari is questionable and I will no longer be using it.

I'm disappointed that Apple has allowed this bug to remain for so long. At a minimum formerly acknowledge it because I still question weather the operating system has been compromised and it's being kept quite.
