All our computers are not able to exclude a new AE block after the update to 1.09.1235, prior to the update we did not have this problem. By design we are to open a program, used heavily in our office, via the 3rd party's ribbon in Word. Though listed in the log the exclude button remains greyed out so right now we can only stop protection. I have cleared the logs and reset the default but this did not resolve like it did with nick-d. Please find zip directory Malwarebytes Anti-Exploit with all files. Should note this is a trial version to see if I could replicate the problem which I could, all affected 10 systems are paid versions.
