Steps to reproduce:
If I click on different layers in various comps, the ECP often fails to update; it might still show the effects controls for a layer I selected some time ago. I've never seen this issue before, and it doesn't happen (on the same project) in the release version (24.3.0 Build 50).
Also, sometimes if I enter a value on a layer's effects (eg. the amount of Gaussian Blur) when I press Enter to exit the number box, AE opens that layer.
UPDATE: Yes, this DOES happen with the same project in the release version! Very weird. I would be happy to send the project (not publicly) to Adobe for analysis.
