The phenol red dye reacts with bromnine levels in excess of 8-15ppm and causes it to turn a hot pink or royal purple on most test strips / testers. You are well advised to purchase a Taylor K-2106 kit as there is not actual scientific method to get accurate pH readings from a test strip anyway. You can try using a product to remove the bromine or lower the bromine levels and try retesting if you need a solution working with what you have.

Bromine is not stabalized so leaving it exposed to sunlight will absolutely lower your bromine levels in a hurry.
