Astral Portal effect not playing opening/closing animations

Prefacing this by mentioning that this bug has been reported on the forums a few times in April, but I've supplied a link to a video that may be helpful in noting the exact issue.

Purchased the Astral Portal effect yesterday evening. It is not playing its animations correctly when portals open and close. The "idle" portal animation does play while portals are open.

Specifically, the portals will have a bit of a shimmering effect when closing, but then abruptly pop out of/into existence, unlike the animations in the official preview video.

An image wouldn't be sufficient here, but I have a link to a video I recorded in my hideout.
