Collapse-Pro-Matic Version 1.0.3 issues on Google Chrome

On Google chrome the plugin gives a strange overlapping text

see: https://www.spectrum-ifa.com/financial-advisers-in-spain/

As you click on one of the cities, the content is overlapping the original text. On all other browsers, there is no problem.

Any way to solve this?
