I see that you have quite a few layers sitting on top of each other in that component. Those actually make it hard for you to select and edit elements hiding beneath them.
Here are the culprits that are preventing you from editing the content in the columns:
1- you have
.home-services which is not allowing you to access the columns inside it
2- You have a div called
.service-border which is sitting on top of the other layers and preventing you from editing the layers underneath. ( I would give this div a z-index of negative value)
Please, let me know if this is helpful. If not, I'm happy to help further.
All the best,
