Is anyone else having issues with getting the biofuel and hyprid buses to work with Improved Transport Manager 0.1 https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=2888964436 in a city started long before ITM?

I'm seeing issues with bus lines asigned the biofuel, hybrid, or pure electric D3S buses.
Although my map has 0 (zero) non-biofuel, hybrid, or electric buses, unless I add a diesel bus depot to my city no buses can be added to an existing line, nor can I get buses to spawn for a brand new line.

When ITM is installed, the bus type and depot slots (each CAN be selected, including multiple choices each - if none selected, random of each will be used, ie each new bus comes from any of the available depots, not all from one random, and each new bus is randomly chosen, so you will suddenly have a plethora of different bus types on your bus line.)

After adding a non-biofuel depot to my city, I've seen seen bus lines using the D3S buses suddenly send every bus back to the depot, and they all return to a biofuel depot, which proves that CS understands that they use biofuel depots, and yet until the diesel depot is placed, I cannot get any of my biofuel depots to spit out a single D3S bus.

Am I the only one, again?
