Locally everything is fine, but the hosting does not have the necessary indents, where to look?

Question

Vue.js

Good afternoon. The situation is approximately the following. One fine day, some indents disappeared from the site. It doesn't show up locally. I tried to update local vendors with the command npm install, everything is displayed as it should. I also tried to build with a command npm run build(I usually work on npm run serve) and configure through virtual hosts, everything is also good. And the sale is not good. What could be the matter in this case and where to look for a bug?
