AP Invoice Tax Line Distribution Class Incorrect

When create invoice matching PO, click calculate tax button, the tax line can be created.

But when click distribution for this tax line, the distribution class shows as saved but there is no tax data in ap_invoice_distributions_all table.

After close the distribution form and open it again then click save button again, the tax data can be created or shown in distribution table then.

p.s-If just create standard invoice without any matching, after click calculate tax button, the distribution class field shows as 'previewd' and after save action, it shows as 'saved' and data shows in distribution table also.
