image spacing

https://www.accountantswebdesign.us/accounting/accounting-technology
In the clients element at the bottom of the page, there are some icons that are not spaced evenly to the next. For expample, The Shopify and XERO and Expensify images are more to the left than they should be.
I haven't been able to find anything that would affect all images equally.
Can you let me know what I need to do please?
Also, the auto slide is set to on, but once it gets to the end of the items, it doesn't keep going from the start again. Should it?
Thanks
