TOC Hyperlinks not showing in Hyperlinks window

Now that my company has upgraded to InDesign CC 2019, I am finding that TOC hyperlinks to Page are not appearing in the Hyperlinks window. We update the same documents year after year, so these documents would have been created in earlier versions of InDesign and in earlier versions, you could click on the Hyperlink in the Hyperlinks window and check the settings and see right away if the Hyperlink had a red flag next to it. Now the only way to access the link is to select the entry and right click on it and select Hyperlinks... Edit Hyperlink from the pop up window. This is time consuming to do in a long TOC. On some entries, you can't even access the Hyperlink from the pop up menu. And you can't access New Hyperlink... from the Hyperlinks window because it is grayed out, which tells me it must already be a Hyperlink, but I can't access it to delete it or update it or do anything to it. Can anyone tell me what might be happening?
