I noticed this is the same for the Android version too. It wouldn't necessarily be a bad thing, except that when you scroll down to read your 7-day load score and the accompanying description, it only applies to the last 7 days in the chart. I am going to see if I can submit a bug report for this.
OK, so I did a little more playing around with the 7-Day Training Load chart in both Garmin Connect Mobile and Garmin Connect Web and surmised that this is NOT a bug and everything is working adequately and as intended. Each dot on the chart represents a 7-day moving average score for your training load. The text at the bottom of the chart (which is cut off in your picture) tells you what your current training load is for the past 7 days. You can also click-and-hold on the chart and it will tell you the 7-day training load score for any of the individual dots on the chart.
