If you have 2 or more authors with the same last name, EndNote will add author initials to the citation to distinguish between them. If full author names are not entered consistently in your references, you will find that initials will appear in-text even when you are quoting different works by the same author. See Remove author initials from in-text citations on the Insert, edit and delete citations page of this guide. The first 2 parts of the process for removing author initials from in-text citations are here.
If tidying up all of the author names in your Author Terms List and individual records doesn't fix this issue, and you do not want any initials in the citations in your document, you can edit the output style to turn off this feature.

You can modify the citation templates of any style to use superscript numbers for in-text citations. If you are already using a numbered style, you only need to modify the Citation template. For other styles, edit both the Citation template and the Bibliography layout. Choose the style you need for your reference list. For these examples, I’ve used APA 6th and Vancouver.

The referencing style you have chosen may be set up to create a List of Figures at the end of your document, as in the example below. If you want your figures to appear in text, but your figure is not appearing at the point in the text where you tried to insert it, you will need to edit the style.
For this example I am using APA 6th. You can edit any style you choose.
