To change the title of a block on your homepage follow these steps:
Log into your dashboard and select the "Edit Site" tab from the left-hand side toolbar.
Within the draft version of your site, locate the block you wish to update.
Hover your cursor over this block.
A pencil icon will appear in the top right corner of the block. Click on this "Pencil Icon".
After clicking the icon, select "Configure Block" from the options presented.
In the configuration settings, you can now change the "Block Title" as needed.
While making changes, ensure that you do not alter any other settings to prevent the unintended removal of your block.
Once you have updated the title, scrol down and finalize your changes by clicking "Save".
