You should have stated a few more things in your question. This is an extension. You fail to mention what LO version you are using, the extension version you are using, the function it fails on, the language used and your OS for starters. I have loaded v1.4.2 of this extension in LO v5.4.3.2 on Mint 18 in English and some basic testing produces no problems. If you have specific problems it is best to contact the author - found here.
