We have corrected this problem. On July 24, 2014, we started a phased rollout of updated build 15.0.4631.1004. A growing number of users will start to receive this fix during this gradual rollout. After the update is made available, users who want to apply the update immediately can do this manually. To obtain the latest Office build, click File, click Office Account, click Update Option, and then click Update Now on the options list.
