I am attempting to create a map without a few city symbols - specifically Nairobi, Kenya (top right) and Moroni, Comoros (middle right). I have tried excluding them in definition queries. Then, I ended up deleting the rows in the attribute table for those cities. Yet, for some reason, those points are showing up in my final exports.
Here is an image of what it looks like in layout mode (before export):
Notice how there is no hexagon symbol to the east of Kigali and southeast of Dar es Salaam.

Here is an image of the exported product:
Notice the hexagons have shown up after exporting.

Any assistance on how to resolve this issue would be much appreciated! And yes, I have also tried restarting the software. This is using ArcGIS Pro 2.6.0
