Let’s keep this post pertaining to the text moving. If you want to discuss the quotes then please post a separate post. Those are 2 completely different issues. To make it cleaner and less confusing for anyone searching out issues in the future, it is best to keep each post focused on a specific issues and not convoluted with different issues.
1. For the text layer, is it set up as point text or paragraph text?
2. Are there any hard returns in the text setup? I have seen this happen when the text layer was setup with empty lines above the text. Then when it replaces the text, it removes the empty lines and the text shifts.
If neither of these are the issues then please delete the text layer and create a brand new layer to replace it. That will most likely fix it. Let me know.
