[Bug] Data misalignment in imo-bench-algebra-036 in Answerbench_v2

## Description
I found a data formatting issue in the Answerbench_v2 dataset. Specifically, in the file answerbench_v2.csv, data: **imo-bench-algebra-036**, the columns are misaligned. The ``Problem`` and ``Short Answer`` fields appear to be merged into a single column, causing a missing column in the dataset structure.

\[
a Y\left(a+\frac{1}{b}\right)+b Y(b)+\frac{a}{b}=b Y\left(b+\frac{1}{a}\right)+a Y(a)+\frac{b}{a}
\] [Bug here]
