Cobalt buttons dissapear after once they get used

This is screenshot of my console, first 2 warnings refferenceerrors are displayed from page load, but last two appeared when I clicked on a MY menu item in markup template of listing page and after that click that menu item has dissapeared.

There area also many other warning in jquery and mootools but not any error.

Both templates are Bootstrap 3 but, on one Joomlart Intranet I don't have same problem, on Omegatheme Shirt I have problem.

Is there any solution or do I need to second template?

Hello Giorgi625,
this is a very well-known issue!
I remember, Joomlart T3 implemented some fixes and JS tricks.
But many other Bootstrap3 templates have this issue.
Actually you are a lucky guy, because I had to wait for many weeks and months to get a solution. ;)
Eventially, I found out that it can be fixed by simple CSS.

Here is a common example for Joomla core stuff:

*[data-toggle='tooltip'], 
.hasTooltip 
{
    display: inline-block !important;
}

But sometimes you might have other elements and classes on your site.
So you have to specify and update that rule(s)...

For your current Cobalt markup it seem to work for all Tooltips with:

*[rel^='tooltip']
{
    display: inline-block !important;
}

Or you can try this specific one for the a-tag, which has a class filter-link:

a.filter-link
{
    display: inline-block !important;
}

Add one of the last two rules to your custom.css
If you have other vanishing elements, identify their classes or attributes and add them to the rule!
