Simulink: Signal Scenario editor with large datasets

I am looking to import a large signal data vector. Presently I have >80,000 data points to simulate in a Simulink model.

I have imported the signal and can see its structure (See capture). I have imported the data in two vectors (Capture 1) and used the block parameters in Capture 2.

Presently I am getting the following message:

Error occured in ***********

Caused by:

Invalid data for signal 'Signal'. The data must be a built-in numeric, logical, fixed point or enumerated type. Data must be finite (not Inf or NaN).

Component:Simulink | Category:Block error

Is this potentially due to the size and noise in the dataset? I'm looking to use a number of these signal blocks so want to understand what the issue is before I move on.
