Submitting the MWE of the issue you're asking about is as easy as copy/paste from your .tex file into the question window.
That's it. That's all there is to it.
We could ask for a copy/paste of the essence of a working example of the problem from your .tex file, but it's shorter to say, "Please submit an MWE."
@Troy recommends using the "{}" feature in the website.
"What's that?" you ask, because you're new to the site? There's an orangish, redish link right above this box labeled "advanced help" that takes one to the additional details on the features available in this window. There are many features, and the one of focus for submitting an MWE is the "{}" button. If all else fails, just push a few buttons and see what happens. Nothing is submitted until you submit it.
Those new to the site may also benefit, as this author has, from knowing that where one pre-indents one's code before copying, the necessary leading four spaces on each line that this website needs for "knowing" that what's being placed into the window intends to be code, are already in place.
@Troy's approach is more efficient, once one gets the hang of it.
@marmot, @Werner, and others, also admonish understanding "minimal," which is addressed in the "dissertation" found here. Some typesetters have very long and involved documents, and what "minimal" encourages, basically, is removing everything that doesn't matter for the problem. (Yes, make a copy of the original, of course, and prune the copy down to the MWE.) At the extreme bottom of that "dissertation" is the needle in the haystack provided above.
We look forward to addressing your question. Having the MWE typically makes processing your question that much more time efficient.

isn't interpreted the way you want it to, so newcomers may find it strange. In regular text, LaTeX would suffice. For more, see my comment to your answer.
