Modelica.Fluid.Vessels gives error when called.

[90PlusWorks]

I'm calling this from the StirlingTypeAlpha_ex01 or StirlingTypeAlpha_ex02 or StirlingTypeAlpha_ex03 code:
Modelica.Fluid.Vessels.ClosedVolume volume(redeclare package Medium = engineAir, V = 0.1 * Modelica.Constants.pi / 4 * 0.1 ^ 2, nPorts = 2, use_portsData=false) annotation(
Placement(visible = true, transformation(origin = {10, 170}, extent = {{-10, -10}, {10, 10}}, rotation = 0)));

and it gives the same error for all three:
[2] 13:52:49 Translation Error
[Modelica.Fluid.Vessels: 253:9-254:130]: Non-array modification ‘false‘ for array component ‘fixed‘, possibly due to missing ‘each‘.

In line 252-3 of Vessels, this is the line:
// Note: should use fluidLevel_start - portsData.height
Real[nPorts] s(each start = fluidLevel_max)
"Curve parameters for port flows vs. port pressures";

Since nPorts = 2, and "each" is not missing, what other error could do this?
