Several issues to unpack here.
Are you actually starting with a TL of 4 or is your historical data not uploaded to Xert yet?
Until you reach 1 star status your training level is classified as Untrained so rather than follow a plan you could simply ride as you wish for now.
There isn’t much value in forecasting a plan with a target date that far into the future (148 days from now). As you get closer to 100-120 days out you can start an XFAI plan to populate the Planner. In the meantime, you are better off with Program set to Continuous with a blank calendar as you raise your TL. You’ll be following XATA guidelines with a selected focus duration and improvement rate while you learn Xert. This will more closely match the current docs and videos as XFAI Beta content is in flux.
The workout library is limited at the 1-star/1-diamond level. As you reach 1-2 stars library selections will expand with many more matches to choose from.
Autogen is your best bet to generate a workout that matches the XSS ratio goal for the day when optimal selections are limited or not found.
There can be a range of workouts that achieve the same goal based on distribution of low, high, and peak strain and RIBs (rest-in-between). Over time you’ll learn how to quickly identify the differences by the color-coded thumbnail charts, MPA drawdown line, and difficulty (shaded portion of the chart). If you mark your favorite workouts, they’ll appear higher on suggested lists in the future or disklike ones you prefer to bump down.
Also consider the training advice will include instructions on how you might free ride outdoors without following a structured workout and achieve the intended strain goal for the day. That is a learned skill worthy of a separate topic. 
Lots of newbie tips are in my onboarding post if you haven’t read that already.
Welcome aboard.
