Not in the events.log. events.log logs out all the state changes for all of the Items regardless of binding and since you are using Simple Mode, an Item gets generated for all Channels of all Things.
The name of the item in the log looks like a Thing ID. In simple mode OH creates an item for each Channel using the Thing ID. People tend to name their Items something more human friendly.
I’m guessing you are either now using Simple Mode or you have at some point in the past. Or you actually created these items with the same name as the Channel they are linked to.
