OK.
Low stabilizer; high CC, though I don't fully trust those values. I'd be more comfortable if I was looking at readings from an FAS-DPD kit. It's much more accurate than your dealer's 'goofy strips' plus electronic reader*. The Taylor K2006 is probably the cheapest; Amazon link below (purchase only if the seller is "Amato Ind" -- some of the others confuse the K2006 with the K2005).
Anyhow, the way to remove the bromide -- according to Jock Hamilton who started United Chem -- is repeated shocks + sunlight. So, repeat your bleach doses nightly. That should be enough to eliminate any lingering algae and clean up the CC's. Hopefully, it will also convert the bromide to bromate.
By the way, the chlorine drop during the day, suggests your cover isn't blocking as much UV as you thought. It's something to check -- you may need more stabilizer than you thought, too. If you get the FAS-DPD kit, you can find out.
Meanwhile, you need to think about how you want to operate your pool -- low CYA; high CYA, or salt.
Is this your first year with the pool? How have you done it before?

* All those decimals in your dealer's results are normally bogus. You can check this for yourself, by collecting two samples at the same time, and telling your dealer that you've been losing chlorine overnight, but need a more accurate measurement of how much. (True; it's what the FAS-DPD test is for.) So you have two samples collected from the same pool, but at different times that you need tested. (Also true; just don't tell the dealer the two times were only a minute apart!). Typically, you'll see widely varying results from the same water sample.
