Glossary Widget - Not working by clicking on Letters

Hello,

I am using the Captivate v10.0.1.285 and I am having a problem when generating a Glossary with the Glossary Widget.

My Glossary is composed of more than 300 words and Definitions.

Once published in HTML5, here the behaviour:

Procedure to Reproduce

Test 1: Click on A or B or C letters

Actual: The glossary is going to the first word according the letter I clicked on.

Expected: The glossary shall go to the first word according the letter I clicked on.

Test 2: Click on D or any other letters existing between C and Z

Actual: The glossary is going to a random letter (most of the times 2 letters before the letter clicked)

Expected: The glossary shall go to the first word according the letter I clicked on.

The behavior of the Widget is not good and I am stuck with it. Could you please help me by giving me the solution to correct the problem?

Thanks in advance,
