Taxable Amount and Amount to Distribute are blanked after split a Tax Exempt Voucher

Steps to reproduce:

1) We search an A/P invoice with an Exempt tax area in P0411S form. It has a pending amount of 150.

2) Click on SPlit

3) We enter 100 (by mistake) as pending amount in the fist line.

4) We enter 60 as pending amount in the second line.

5) We get a pending amount of -10

6) We fix the first pending amount to 90

Then the Taxable Amount and Amount to Distribute are blanked. If we save corrupt amounts are saved in F0411

We are on version JDE 9.2. Do you know about any ESU to fix this issue?

Thanks in advance.
