Good Morning 
glad to hear that. My code always works because I test it on your browser before sending it to you 
But the most important thing here is to easily implement this in the software you use. Website developers sometimes opt for the easy way out by making everything global. In fact, there should be additional things specific to each page, but unfortunately, in the software you’re using, the situation is like this. Of course, it’s possible to solve this somewhat through trial and error. Now, the code below will fix the border issue I saw in the drop-down section of the FAQ page. Would you try adding it if this is what you want? Or it could be another style. Also, it would be good if you could provide the exact link to the page where the code will be added. The code for the FAQ page is as follows:
https://inibo.co/pages/stockists
button.label.collapsible-trigger.collapsible-trigger-btn.collapsible-trigger-btn--borders.collapsible--auto-height {
border: 1px solid #dbdcdd;
padding-left: 7px;
}
.collapsible-trigger__icon {
right: 15px!important;
}
.collapsible-content__inner.rte {
padding-top: 15px;
font-weight: 600;
}
.collapsible-content__inner.rte > p {
border-bottom: 1px dotted;
padding-bottom: 5px;
}
.collapsible-content.is-open {
overflow: visible;
}
You mentioned Grid? I believe those are the pages like the one below? If so, I’ve added borders here as well. Additional enhancements can still be made. The design looks good as I’ve seen, but small touches are necessary for the overall software. The codes :
https://inibo.co/collections/ulltimate-gifts
.collection-grid>.grid-item {
padding-left: 0;
padding-right: 0;
border: 1px solid #dbdcdd;
border-radius: 5px;
padding: 20px;
};
What exactly did you want in the Filters section? Would it be just a single line like the one below? If so, could you please try the following code? It needs to work globally.
button.collapsible-trigger.collapsible-trigger-btn.collapsible--auto-height.is-open.tag-list__header + .collapsible-content.collapsible-content--all.is-open {
width: auto;
}
Also, could you provide the exact links to the pages where the conflicting codes were added? For example, if I send you a code and it works but causes issues on a different page, providing the links to both pages with the conflicting code would help us quickly resolve the issue. Additionally, if possible, could you point out the relevant sections in images? 
best regards,
