Navbar组件修改样式不生效

代码编译后不生效
.mint-tab-item-label[data-v-4917ee8b] {
font-size: 16px;
}
在开发者工具中修改为
.mint-tab-item-label {
font-size: 16px;
}
才会生效，
请问这该怎么解决呢？

The report names only the Navbar component and a scoped CSS selector; no source file, reproduction, or test is provided. Start by reproducing the compiled-style behavior in the Navbar component and trace the generated selector. Done means the intended font-size styling applies after compilation without editing it in developer tools.
