When trying to build a dictionary with URL's or multiple choice values, the dictionary will encode those values with extra special characters ("""). when stored.
For example: Action configuration:

The output will be:
{"URL":"https://tenantname.sharepoint.com/Lists/name/DispForm.aspx?ID=id"}
Instructions
Use a "Get an Item from a Dictionary" action to retrieve the required index and the URL will be decoded and saved it in a new variable.
For example: Action Configuration

Output:
https://tenantname.sharepoint.com/Lists/name/DispForm.aspx?ID=id
Additional Information
Due to the structure of a Dictionary variable some special characters need to be encoded when stored so that they do not interfere with the structure.
If the dictionary variable is used as is, it will contain the encoding. When retrieving an entry from the dictionary this encoding is removed.
