Flex container is displayed incorrectly in IE, how to fix it?

Question

Internet Explorer

Hello! I'm laying out the site, the section after the header ( screenshot.su/show.php?img=cc270ec8bbd6399e78b7b8b... is completely laid out, I ran it through the autoprefix and the site works fine and is displayed in different browsers, but not in IE. In this browser, the block moved out ( joxi. ru/Q2KD64bh4QnlqA ) I read the forums and nothing helps
Code:
.offer {
max-width: 1100px;
display: -webkit-box;
display: -ms-flexbox;
display: flex;
-webkit-box-pack: justify;
-ms-flex-pack: justify;
justify-content: space-between;
background: url("../img/line.png") no-repeat;
background-position: bottom;
margin-top: 78px;
}
Thanks in advance!
