You are looking at different data sets here, that's why the information is different. The first one is your Event Category, and it's 249204 events for that category. The second one is the event action of that category.
One event category however could have different numbers of event actions, and as it's showed on your screenshot - the 112576 events are events in this category, with one given action (you can see below the number 112K - 38.32% of the 249K, which means - the given event action had fired 112K times, and it's 38% of all events in the same event category.
TL;DR: You are comparing Event Category vs Event Action, and they may or may not be different numbers, depending on your event tracking setup.
