catch gallery update NOT working in catch responsive pro

The new update in Catch Gallery is broken in Catch Responsive Pro in WordPress classic. Images now come up blurry and in weird sizes with weird spaces. This was NOT a problem before the update. Here's a couple examples: https://explorationvacation.net/2011/05/denmark-spring-itinerary/ and https://explorationvacation.net/2019/07/best-gardens-minneapolis-lyndale-park-at-lake-harriet/ -- it's doing this on all pages new and old with a gallery. They are all using the Tiled Gallery setting. The plugin needs to be fixed, but until then, how can I rollback to the previous version?
