Workout Expired Early?

I am on Week 5 of the FTP Builder plan. I always bike on Monday, Wednesday, Friday and Saturday (I run on Tuesday, Thursday). I’ve always completed them early, I did notice my first workout this week I did with only a few hours left, which was out of the ordinary. I opened the app to check my workout for today (Friday) and it’s expired. I’ve done EVERY workout and I’m almost finished and I missed one. How can this be? I can’t even find where to see when it expired. I’m sure there’s nothing I can do now, but I’m so frustrated. It’s my first workout plan and I’ve been really proud of myself sticking to it. Thanks in advance.
