Hi @Absolute,
Thank you very much for taking the time to post your screenshot… it made this very easy to understand and fix.
The fix will be integrated into the next release (osTicket-Awesome-1.11-v1.1).
If you would like a quicker solution please add the following to /osta/user-styles.css:
.advanced-search .adv-search-val .select2-container--default .select2-selection--multiple .select2-selection__rendered {
height: initial !important;
}
