Leisure time renew is non-chlorine oxidizer (potassium peroxymonosulfate, or MPS). It will oxidize the sodium bromide into active bromine (hydrobromous acid), and that is why your bromine reading is high. You used more MPS than you probably needed. 31 ppm bromine is approximately equivalent to 14 ppm chlorine, so it's high, but not extreme. It will come down quicker if you leave the top off, but you also increase the cost of heating by doing so.
Some of the tests will not work accurately when the bromine level is very high. I know pH will not read accurately above 10 ppm of chlorine, so I assume for bromine that would mean above 22.5 ppm. With the Taylor TA test, did you put the R-0008 indicator dye into the sample and it did not turn green? If that is the case, I would wait until the bromine is in normal range, say below 10 ppm, and try the test again. Your test strips might be a general indicator, but they will not be reliable for actual numbers. Since you put the calcium chloride into the water, it is definitely there. The bromine will not make it go away, but it could affect the test. Oh and one other thing. The purpose of the R-0007 thiosulfate reagent is to neutralize the bromine, so with high bromine, you could add more than 2 drops of thiosulfate before adding the dye.
With your chlorine FAS-DPD test, I assume you know to multiply by 2.25 to get ppm bromine. With a 10 ml sample, that is 1.125 ppm of bromine per drop.
