Issues with Discounts & Pricing Rules in v15.2.35?

Our hosted system just got auto-upgraded to .35 about 2 weeks ago. 

Ever since we have been having issues with our discounts not processing correctly (for walk-up sales, when we click the Discount, it will take the money off but the Finish button will be greyed out).

And also the reporting of them using a "Performance Revenue Breakdown" has not worked properly. If I pull a generic breakdown for a specific season and date range, it will show me every discount and pricing rule that was used during that time. If I change the report fields to include a specified pricing rule, it will show "0 Results." (even if I know for a fact that pricing rule or discount has been used. 

These issues only seem to have started happening when we switched to .35. Is anyone else having the same problem and is it just a glitch with .35?
