Predecssors are not following on in dates | MS-Project forum

Hello Ryan,

Thank you for your question. Without the benefit of seeing your project, my best guess is that the 'Calculate project after each edit' option in your Project app is turned off.

To fix this, please do the following:
Click File > Options > Schedule. Scroll down to 'Calculation'.
Make sure that the 'On' option is selected.

If this doesn't solve your issue, please use the forum again for further assistance.

I hope this helps.

Kind regards
Marius Barnard
