If you can only see the default texts of your template on the images of all your blog articles, you will need to configure the template first. Follow these instructions and you should be good to go:
1) Open the template in the editor
In WordPress, go to Tools > Placid > Templates. Open the template you want to use in the editor by clicking on Edit Template.
2) Check the Dynamic Element Setting
Choose the layer of the element you want to be automatically filled with text by WordPress. Click on the Pencil-Icon on the right of the layer's name. Make sure the checkbox for Element is dynamic is active. You should see a dot in front of the layer name. To find this layer later in WordPress, we recommend you also set a layer name you will remember.
Repeat for all layers you need to be dynamic.
3) Configure your template
In WordPress, go to Tools > Placid Social Images again and change to the tab of the image type you want to set (Open-Graph for Facebook and most other Social Media Platforms, Twitter or Pinterest).
If you have chosen your template in the place where you want it to show up, you should see settings for all of the layers you set as dynamic earlier. You can choose with what information you want it to be filled - f.ex. the Post Titles or the URL of your blog.
