Hi,
Try to add the following code snippet to the Custom CSS area in Theme Settings to fix this issue.
.cart_totals .shipping li {
display: -webkit-box;
display: -moz-box;
display: -ms-flexbox;
display: -webkit-flex;
display: flex;
-webkit-box-orient: horizontal;
-webkit-box-direction: normal;
-ms-flex-direction: row;
flex-direction: row;
-webkit-box-align: center;
-ms-flex-align: center;
align-items: center;
-ms-flex-wrap: nowrap;
flex-wrap: nowrap;
-webkit-box-pack: end;
-ms-flex-pack: end;
justify-content: flex-end;
}
.cart_totals .shipping li > input {
min-width: 13px;
width: 13px;
-ms-flex-preferred-size: 13px;
flex-basis: 13px;
}
Regards
