After Effects Sourcerecattime Expression with Text layer bug

In After Effects, Suppose I'm in the Main comp, its about 30 sec and make a text in between, from 15 Sec to 20 sec and I pre-comp it, to do seperate animations on the text. then I want to highlight the text, and want it update everytime I change, so I use the sourcerecatime expression,

 everything is fine, but when I try to animate word by word, Text layer updates the shape layer at the time of the Main comp instead of the Text Precomp, I used the text animator, 

 So word by word is fine, but the shape layer updates later, I found it out when I created a new text layer on the precomp and put on the same text, it updated instantly with the new text layer.
