Difference in Index sizes in DB02

Can anyone explain why there is a difference in the index size in the transaction DB02.

For example when I look up the table FKKMAZE in transaction DB02 > Space > Single Table Analysis, in the Indexes tab it shows me 4 indexes totaling about 273,000,000 KB.

But when I look at the table from DB02 > Space > History > Table Size History it shows the total index size to be 136,000,000.
