Go2Group CRM Plugin (Jira 8 or later) override some styles in Jira 8.7.1

Hi!

I found that after installations this plugin on Jira 8.7.1 the date picker shows incorrectly:

missed arrows and border:

After disable this plugin that date picker shows correctly:

Also i see that additional classed with prefix ".ui-" was added to the element , like ".ui-icon" which override atlassian styles.

I think it is not correct.

I think that it is a not correct place to post this but maybe we can find Go2Group developers here
