Some discovered portals are not highlighted by the Visited Layer
Description of the issue:
In the attachment below you can see 3 white portals discovered by myself. I know for sure I still haven't interacted with any of them, besides being involved in their creation, however when I turn on the Visited Layer in the Portal History feature only one of them displays the purple circle. The portal that displays the purple circle went online on the 7th March of 2021, while the other two entered the network on the 31st October 2020 and 4th November 2020.
