如果单词太多，deleteBlock会停止工作

I try to use deleteBlock in my template but if there are too many characters / words inside my template, deleteBlock stop working.

For exemple I use a simple template (no formatting at all, new docx file) with this text :

PHP Word
PHPWord is a pure PHP library for reading and writing Word, ODT, and RTF files. This file is the source file of read/write capabilites of PHP Word. The text in red should be changed when writing.
${delete}
PHPWord can apply font formats such as bold, italics, color, underline, strikethrough, subscript, superscript, or highlighted. You may also notice that there’s one text break (empty paragraph) before this one that can be created also by PHPWord.
${/delete}
PHPWord can also format paragraph such as this justified, 12pt before and 12pt after with 1.5 lines spacing paragraph. This formatting can be applied inline or using predefined style as we use to do in Word.

It works, but if I add one paragraph, it doesn't work :

Do you know if there're limitations to deleteBlock ?

Do you know if there's others alternative to phpword and deleteBlock to generate long text from a template ?

Thank for your help, it drives me crazy !
