Yeah, that's a weird bug I know of - the funny thing is, thats the data that EA is sending over. I guess I will need to calculate it on my own and display it.
And you are correct - no worries of corrupting any data. It is only an export, so there is no way to mess anything up or push anything back.
Also, I have an integrity check in place when it is processing the exported data to ensure that it doesn't import data into the wrong league. For example, say you and another person both synced your league on GamerHuddle - if you export your data, it will only update your version of the league and not his. I did this to ensure that, if for some reason someone wanted to keep a clean copy of the league from the start of a season, they could do that.
