I an wondering why my efforts doesn’t sync with the interval im doing in zwift? It reads right in Strava and Training peaks. But in Intervals the efforts is delayed against the interval itself.
Use the ‘Workout’ slider found on the Options menu at the bottom of the activity page, to align them.
If this is for an outdoor ride, the Strava Privacy Circle setting is causing scrambled laps to come in to Intervals. Turn off the Privacy circle in Strava.
If you are following a workout, the slider will be active and you can align the recorded streams with the workout intervals by delaying a number of seconds.
If you just pushed the lap button during an outdoor ride, the reason for them not being correct, is probably the Privacy circle setting on Strava.

Why is my bar grey? You can’t touch that. 
It looks like you are using laps for the intervals. Do you have a privacy circle setup in Strava? If you do the lap data sent to Intervals.icu is often corrupted.
You can probably just use automatic interval detection for intervals that neat. Do Actions → Analyse and untick the “Keep all laps” checkbox.
The workout slider MedTechCD is referring to is for when an activity has been paired with a planned workout.
A privacy circle is unlikely the problem if it’s Zwift, but could it be if the start/finish is hidden; the edit visibility settings?
