excerpt_size and title_limit are ignored

Thanks for this great plugin, but unfortunately there are small problems:
excerpt_size shows the default value of 55 words and title_limit seems to be ignored at all.
[catlist name=”presse” date=”yes” excerpt=”yes” excerpt_size=10 title_limit=40 posts_morelink=”Lesen Sie weiter”]
Version 0.51 is used, wp4.0 with Twenty Fourteen
Please help
