I'm sorry that you are having issues with your T-strip package. Unfortunately the track that the t-strip fits into can get damaged, and I found that (likely) because of this, heating up and reinstalling the old t-strip never lasted for more than a few months.
This is why I replaced our t-strip with acrylic caulk and painted the Ensolite surfaces. I found this to be a much better solution to the missing/damaged t-strips.
Unfortunately, you have now paid for the replacement strips. Can they be returned?
