Repeater lost connection with dataset after creating a new dynamic page.

I have a repeater on the home page which is connected to a dataset.
It was working fine and whenever I previewed it, it would show the data from the dataset on the repeater.
However, when I created a new dynamic page, which has nothing to do with the repeater and its dataset, the repeater doesnt show the dataset items in preview mode anymore even though it shows as connected to the dataset in the editor.
I tried disconnecting and reconnecting to the dataset but it still shows default values.

Only when I remove the dynamic pages does the repeater start working again.
