When I move a title further down my timeline it becomes invisible. It shows normaly at eg. 12min but moving it to 12min 10sec. it just can not be seen on the display`/

The only reports I could find on this were about older versions of FCP -- recommendations were to make sure the title is on top of the video [ in the timeline], or possibly to reset Preferences [always keep a backup], though I can't vouch for either of these suggestions [I'm an audio guy myself]. I've linked to one of MPV's FCPX courses [above] that focuses on titles & graphics -- maybe there'll be something helpful in there..
