The 30-day trial includes a subset of workouts from the Standard library folder.
Pre-base phase with Maintenance improvement rate is more or less free-to-experiment mode. 
You will get a variety of workouts suggested in pre-base at/above/below focus for the selected athlete type. You decide which direction to take things.
You can also use Filter and select a different focus and duration to see what differs.
If you want to force endurance phase now you can set a TED less than 120 days out. Ex., April 10th. Base phase is 45 days long.
Xert is a three-level strain model (low, high, peak) where anything below TP is considered low intensity. That means endurance level workouts will include SS and tempo intervals. However, most SMART workouts float through those zones and don’t hang there like old-school %FTP blocks. That makes a big difference IME. I assume you’ve seen my Base to TED experiment.
Time-Triallist focus could result from any momentary rises above LTP during that recovery workout. Since you don’t have a smart trainer to tightly control wattage, my guess is you are spiking a bit.
Post the workout reports for those activities if you’d like so we can see details. Select

Note the endurance quadrant in this chart –
Was your VO2 workout sourced and performed elsewhere?
Even a VO2 workout can end up classified within the endurance quadrant.
Compare this one to this one. Note differences in MPA drawdown and difficulty (shaded portion).
The Progression chart table reflects the athlete type currently selected under Goals.
Are you populating the Planner for the week ahead with workouts you selected manually?
The Planner is a what-if-I-do-this tool rather than a traditional calendar to populate.
You would normally leave it blank when following a phased progression and instead make daily selections based on recommendations for each day.
You can view workout activity details and enable Target Power beneath the chart to compare your compliance to targets.
