Summary:
I have created two periodic trend tags, each with a different sample rate. When I display them both on a trend graph, the trend with the smaller sample period updates incorrectly. When I display the trend cursor, the times shown for this trend are prior to the actual trend times.

Solution:
For versions from 5.31 onwards you CAN display trends with mixed sample rates on the same trend graph. Prior to this there is an interpolation problem so you were limited to only displaying trends with sample rate trends on any one trend graph. This also applies to Event trends with different sample rates.
