Fixed Bump not possible

Device: PC
Browser: Chrome
OS: Win10

Steps to reproduce:
I read that there should be "bump" button on trades which should be active after 24 hours.
I got below trades which i created on 31 Oct was able to bump on 1 Nov after 24 hours. But now even 24hours has passed i'm not able to bump it.
Is there limitation of one bump per trade? Or some bug?

trade/crafted-blood-gloves-20ias-with-mf-t352303.html
trade/nosferatu-s-coil-t352347.html

Please advise.

I have the same problem, chrome win10.
I noticed the time stamps on the post will often be wrong (say posted 14hrs ago but was in fact 2days ago)
Then I dont have the bump option, and all my listings expire
