Alexa 35 Sync Issues

Hi there, I am having issues syncing my timecoded Alexa 35 footage in Tentacle Sync Studio, has anyone encountered this issue before and if so, did you find a fix? The DIT on set made proxies from the Alexa 35, and those proxies seem to have the correct TC, so it can be read, but weirdly Tentacle Sync Studio just seems to be unable to read the files. Have attached image below. Any help would be greatly appreciated
