Data labels not displaying properly on line chart

So I've created a line chart in Power BI with data labels. The labels show up fine on the desktop version, works great.
I've pushed this to the online version, and on the online version the labels don't show up. As I start to filter to narrow down the chart, the labels might appear, but also seem to get "stuck". I'll click on different filters and the lines themselves will change and update based on the new information, but the labels will not change and stay "stuck" in their original place (I almost thought it was a video card error if I wasn't able to duplicate it).

Perhaps I've done something wrong, and if that's the case let me know. But this issue was just recently noticed in a report that has been published for the last month or two, so I'm wondering if it has to do with an update to Power BI online.

One additional note is that not only do the labels work fine in Power BI desktop, they also work fine in the iPad app version as well. So far I've only encountered this issue in the online version.

Any ideas on what could be causing this?
