Text animation not playing in some blocks

I am currently working on a project using Adobe Captivate 12.5 and have encountered a few issues that I would appreciate your assistance on. this is my first Captivae project, and here's one of the issues I encountered:

• I hid blocks on publish and set them to progressively appear once the previous block has finished playing.
• When a block becomes visible, I want to animate the text using the "Typewriter" entrance animation.
• Since the built-in interactions only include emphasis animations, I manually added entrance animations for the text.
• This method worked for some blocks but did not work for others, even though I ensured the settings were consistent across all blocks.
• Is there a known issue with text entrance animations when used in this way, or is there a recommended approach to make them work consistently?
